Parameters and settings

Basic member check parameters Safety factors

gamma M1 Safety factor.

gamma M2 Safety factor.

Default sway types

These default sway types are used for all members, unless the user changes them in the settings made for particular members. The sway type (with or without bracing) is used for calculation of buckling length ratios.

Y-Y If ON, the members are sway in Y-Y direction.

If OFF, the members are non-sway in Y-Y direction.

Z-Z If ON, the members are sway in Z-Z direction.

If OFF, the members are non-sway in Z-Z direction.

elastic check only If this option is checked, all members are assessed to elastic check only and no shear buckling check is performed.

section check only If this option is checked, only the section check is carried out. No stability check is performed.

Buckling length ratios ky, kz

Max k ratio The calculated value of k is limited and must not exceed the given value

Max. slenderness If the slenderness of the checked member exceeds this value, the program prints a warning in the output report.

2nd order buckling ratios

According to input

The buckling data are considered in the 2nd order analysis by values as they were defined.

All non-sway

The whole structure is considered as non-sway.

Calculation of xs for unknown buckling shape

The value xs is the distance from the studied section to a simple support or point of contra flexure of the

deflection curve for elastic buckling of axial force only. If we do not know the buckling shape, there are two option how the value can be determined.

Use half of buckling length

A half of the buckling length is used as the value of xs.

According to EN 1999-1-1 formula (6.71)

The value of xs is determined according to the mentioned formula from the code.

Calculation of xs for known buckling shape

If we know the exact buckling shape, there are also two option how the value can be determined.

Use half of buckling length

A half of the buckling length is used as the value of xs.

According to buckling load case

The value of xs is determined from the buckling load case.

Only LTB stability check in 2nd order calculation

If ON, only the LTB stability check is performed for 2nd order calculaton.

The procedure to adjust the basic member check parameters


4

1. Open service Aluminium:

a. either using tree menu function Aluminium,

b. or using menu function Tree > Aluminium.

2. Select function Beams > Setup and open it.

3. In the dialogue that appears on the screen, select tab Member check.

4. Type required values and select appropriate options.

5. Confirm with [OK].

Relative deformation parameters The maximum permissible relative deformation may be adjusted separately for individual 1D member types:

general member,

beam,

column,

gable column,

secondary column,

rafter,

purlin,

roof bracing,

wall bracing,

girt,

truss chord,

truss diagonal,

plate rib.

The procedure to adjust the relative deformation parameters





3. In the dialogue that appears on the screen, select tab Relative deformation.



Alternative values setup This tab shows a table with radio buttons to choose between the default method or the alternative method to calculate specific parameters. In addition, the table also shows the reference of every particular parameter within EC9.

By default all parameters are calculated using the 'Default' method.

Some parameters in the table are greyed (disabled) as they are linked to another parameter in the table and it would be illogical to use the default method for one parameter and the alternative method for the other related parameter.

The procedure to adjust the alternative values of parameters





3. In the dialogue that appears on the screen, select tab Alternative values.



National annex This tab shows all parameters defined by the National Annex. In addition, the table also shows the reference within EC9.

3. In the dialogue that appears on the screen, select tab National Annex.



Buckling defaults The default buckling parameters are used whenever a new aluminium 1D member is input into your project. By default, the new member takes these default parameters. If required, you may later alter these default values and assign specific values to the particular member.

Buckling system relation

zz System length for buckling around the local zz axis (weak axis). This is usually the length between the points braced in the direction of the local yy axis.

yz System length for torsional buckling. This is the length between the restraints for torsion.

lt System length for lateral-torsional buckling. This is usually the length between the points braced in yy direction (= length between the lateral restraints).

Relative deformation systems relation

def y System length for deformation around the local yy axis (strong axis).

def z System length for deformation around the local zz axis (weakaxis).

ky factor Calculate

The value of the ky factor is calculated by the program.

Factor

The user defines the value of the factor.

Length

The user inputs the buckling length directly.

kz factor ditto for kz factor

Influence of load position

This field is relevant for lateral-torsional buckling check. It provides for consideration of destabilising loads in moment factors for LTB.

Destabilising loads are loads that act above the level of the beam’s shear centre and are free to move sideways with the beam as it buckles (and produce a disturbing effect)

The procedure to adjust the buckling defaults





3. In the dialogue that appears on the screen, select tab Buckling defaults.



Member settings The user may define parameters for each member in the structure separately. The parameters defined in this way are called "member data".

Buckling member data This group of parameters specifies where the member data relating to buckling are taken from.


Member material Informs about the material for which the data are being defined.

Buckling ky, kz coefficient or buckling lengths

Selects from where the buckling data are taken (see below the table).

All other and LTB coefficients

Selects from where the other buckling data and LTB data are taken (see below the table).

The data can be read from three different sources. Let us describe shortly all of them here.

From standard analysis

The coefficients are determined on the basis of the standard analysis. The program generates fictive load cases and uses the results to calculate (estimate) the buckling coefficients. These calculated coefficients should not be treated as a dogma, but the user should evaluate them and decide whether the numbers are relevant o the conditions in question.

From stability analysis

The coefficients are determined on the basis of the stability analysis that must have been already performed.

Default from LIB manager

The data are read from the Buckling data library manager.

Each beam (made of any material) has a set of properties that can be displayed in the property window when the beam is selected. One the properties is Buckling and relative lengths. There, you can assign the required buckling data set from the Buckling data library manager.

User input

The user inputs manually all the required coefficients.

The procedure to adjust the member buckling data




2. Select function Beams > Stability Check Data > Member buckling data and open it.





Lateral-torsional buckling settings LTB restraints are supports against lateral-torsional buckling (LTB) at the top or bottom flange of the beam. The topside is defined by the positive local z- axis of the section. It means that for a positive My (which causes compression at the topside) the LTB length (and the related moment) is calculated by the position of the stiffeners at the topside. The bottom side is defined by the negative local z-axis of the section. It means that for a negative moment My (which causes compression at the bottom side) the LTB length (and the related moment factors) is calculated by the position of the stiffeners at the bottom side. When no LTB stiffeners are defined, the values, introduced in the Buckling data dialog are used.

Name Defines the name of restraint.

Position z Specifies the position in Z direction, i.e. either the topside or the bottom side.

Geometry

Position x Defines the position of the restraint.

If more than one weld is being used, this value specifies the position of the first weld.


10

Coord. definition The position can be input in absolute or relative coordinates.

Repeat Defines the number of restraint.

This number includes the restraint at the beginning and at the end of the defined interval. If the "on begin" restraint or the "on end" restraint is not included, the actual number of defined restraint is lower (by one or two) than the value defined here.

Regularly If ON, the restraints are distributed regularly over the length of the beam.

If NOT, the following parameter (Delta x) specifies the distance between the adjacent restraints.

Delta x This value specifies the distance between the adjacent restraints.

On begin If ON, the first restraint is defined.

If OFF, the first restraint is not included.

On end If ON, the last restraint is defined.

If OFF, the last restraint is not included.

2. Select function Beams > Stability Check Data > LTB restraints and open it.





Stiffener settings Web stiffeners are used to prevent shear buckling, which can be a design failure mode for high and slender (thin webs) profiles.

Name Defines the name of the stiffener (set of stiffeners).

Stiffener

Material Specifies the material used for the stiffener.

Thickness Determines the thickness of the stiffener.

Decrease The actual size of the stiffener can be reduced by a specified value (a millimetre or so) from each side of the stiffener to make the stiffener smoothly fit between the flanges.

Geometry

Position x Specifies the position in X (longitudinal) direction.

Co-ordinate definition Defines the co-ordinate system in which the position x is inputted.

Repeat Tells how many times the stiffener is repeated.

Regularly Tells that stiffeners are positioned regularly with the same distance between two adjacent stiffeners.

Delta x Defines the distance between individual stiffeners.

This item is available only if Repeat is greater than one.

On begin Specifies whether the first stiffener should be applied.


11

2. Select function Beams > Stability Check Data > Stiffeners and open it.





Diaphragm definition

Name Name of the diaphragm.

I moment Moment of inertia (i.e. second moment of area) per length.

K1 + Factor K1 for positive position.

K2 + Factor K2 for positive position.

K1 - Factor K1 for negative position.

K2 - Factor K2 for negative position.

Geometry

A Dimension A: see the Fig. below.

B Dimension B: see the Fig. below.

C Dimension C: see the Fig. below.

D Dimension D: see the Fig. below.

Thickness Thickness of the sheet.

Nominal thickness "Nominal thickness" is the "gauge value" whereas "Thickness" is the "actual thickness" of the profile deck. This value is used ONLY for Composite beam design checks. It is not used in normal aluminium design checks.

The dialogue for the definition of a diaphragm is the same for both steel and aluminium structures, thus the value is present here as well. It has no practical meaning for aluminium structures.


12

The procedure for definition of a new diaphragm

1. Open the database manager for Diaphragms:

a. either using tree menu function Library > Diaphragms,

b. or using menu function Libraries > Diaphragms.

2. Click button [New] to create a new diaphragm.

3. A new diaphragm is added into the list of defined diaphragms.

4. Click button [Edit] to edit its properties.

5. Input the parameters.


7. Close the database manager. Note: A new diaphragm is defined in the program tool called Database manager. The database manager can be used not only for the definition of a new diaphragm, but also for editing of existing ones, for removal of no more necessary ones, and for other operations related to the management of diaphragm database.

In addition, other settings must be made in order to apply the diaphragm in a structure model.

Diaphragm settings The diaphragm is completely defined by means of:

basic geometrical parameters,

settings determining its position in a model.

The settings for the diaphragm are:

Name Name of diaphragm settings set.

Diaphragm Lib Type of defined diaphragm.

k The value of coefficient k depends on the number of diaphragms:

k = 2 for 1 or 2 lateral diaphragms,

k = 4 for 3 or more diaphragms.


13

Diaphragm position The position of the diaphragm may be either positive or negative.

Positive means that the diaphragm is assembled in a way so that the width is greater at the top side.

Negative means that the diaphragm is assembled in a way so that the width is greater at the bottom side.

Bolt position Bolts may be located either at the top or bottom side of the diaphragm.

Bold pitch Bolts may be either:

in every rib (i.e. "br"),

in each second rib (i.e. "2 br").

Frame distance The distance of frames (i.e. the span of transverse bonds).

Diaphragm length The length of the transverse bond.

Geometry

Position x1 Value x1 specifies the begin-point of the diaphragm on the beam.

Position x2 Value x1 specifies the end-point of the diaphragm on the beam.

Co-ordinate definition Defines the co-ordinate system in which the position x is inputted.

Origin Defines the origin from which the position x is measured.

Type of analysis Eigenproblem (Mcr) (= calculation of Mcr for LTB)

2nd Order analysis– according to code - elastic check (=2nd Order, inclusive warping analysis, only valid for DIN, ONORM and EC3-EN)

2nd Order analysis – according to code - plastic check (=2nd Order, inclusive warping analysis, only valid for DIN, ONORM and EC3-EN)

2nd Order analysis – general (=2nd Order, inclusive warping analysis) (valid for EC3-ENV, EC3-EN, DIN, ONORM, NEN, SIA)

Cw i The additional end condition for Cw (warping spring).

Warping condition at end i (beginning of the member).

Default values :

- v0 - imperfection (in direction y local) [m] = 0.0

- w0 - imperfection (in direction z local) [m] = 0.0

When ' 2nd Order analysis– according to code - elastic check' or '2nd Order analysis –according to code - plastic check', the imperfection v0 is calculated according to the code regulations. The value for w0=0.0.

The value v0=e0/2.

w0 See above.

Linked beam

Linked beams To take into account loading and stiffness of linked beams, set this option to ON.

Application point The position of the restraint z(Cy) or y(Cz) is depending on the application point of the linked beam. It may be either top or bottom. The position is only taken into account in case of a flexible restraint.

Type of restraint Two types are available: fixed restraints and flexible restraints.

c If 'flexible restraint' is chosen, the spring value is input by the user.

2. Select function Beams > Stability Check Data > LTBII member data and open it.





15

Performing the checks

Prerequisites of the check Before the user may get down to the business of checking, a set of specific conditions must be met.

1. The model of the analysed structure must be properly defined.

2. The boundary conditions and loads reflecting the real conditions of the structure must be specified.

3. The model of the analysed structure must be calculated, in other words, the internal forces and deformations must be known.

General principles of checking The procedure used for performing the checking is analogous to the procedure for evaluation of results.

It can be summarised by the following points:

1. Opening of the required service.

2. Selection of beams that should be checked.

3. Selection of load case or load case combination that should be used.

4. Adjusting of display parameters.

5. Selection of values to be displayed.

6. Displaying of the results of the checking.

Service Check

The required type of check can be selected in the tree menu of service Aluminium > Beams. Once the type of the check is selected, the appropriate parameters are listed in the Property window.

Parameters common for most of the available check types are:

Selection The user may display the results either on all or only selected beams.

Load type Specifies what "load type" is considered for the display. Available load types are:

load cases,

load case combinations,

result classes.

Load case / combination / class

For each of the above specified load type a set of available items (load cases, combinations, result classes) is offered.

Filter The set of beams where the results are displayed may be specified by means of a filter.

Values For each of the result groups (unity check, fire resistance check, etc.) a set of quantities is offered for display. The user may select which one is really shown.

Extreme The numerical values may be displayed in specified extreme points.

Drawing setup It is possible to adjust the style of the diagrams.

Other specific parameters Some of the available result groups (unity check, fire resistance check, etc.) may have other group-specific parameters.

Selection of members

The result diagrams may be displayed on:

all the beams in the structure,

selected beams only.

Which variant is actually applied can be adjusted in the Property window by means of parameters Selection and Filter.

Selection


16

All If this option is selected, the result diagrams are displayed on all beam members in the structure.

Current The result diagrams are displayed on all the currently selected members.

Advanced This option allows the user to display diagrams on selected members. It is similar to the previous option but offers something more. See below the table.

Named This option allows the user to select one of the previously created, named and saved selections.

Selection: Advanced

With this option, you may select required members on which the results are to be displayed and review the results. Then you may clear the selection. The result diagrams, however, remain displayed. Now you may make a new selection and invoke the refresh of the screen. The program will ask you what to do. The available options are:

Use current selection

The result diagrams displayed during the last refresh are deleted. New result diagrams are displayed on the currently selected members only.

Add current selection to previous selection

The result diagrams displayed during the last refresh remain displayed. New result diagrams are shown on the currently selected members.

Use previous selection

The current selection is ignored. The result diagrams displayed during the previous refresh remain displayed.

Subtract current selection from previous selection

If there is a result diagram currently displayed on one of the currently selected members, this diagram is hidden. The result diagrams that are shown on members that are not in the current selection remain displayed.

Filter

No No filter is applied.

Wildcard The set of beam members for display is defined by a wildcard expression.

E.g. expression "N*" lists all entities whose name starts with letter N. The expression "B??" lists all entities whose name starts with letter B and is followed by two characters.

Cross-section Diagrams are shown only on entities of selected cross-section.

Material Diagrams are shown only on entities of selected material.

Layer Diagrams are shown only on entities inserted into selected layer.

Displaying the results after re-adjustment of check parameters

Whenever the settings in the Property window of service Check are changed, the diagrams on the screen usually require regeneration. Because the fully automatic regeneration could be very slow for excessive models, it is up to the user to regenerate the drawing when necessary.

Any time the user makes a change that affects the display, the program paints the cell Redraw of the Property window in red colour. Until the user presses the button [Redraw], the cell remains highlighted.

Performing the resistance check The resistance check offers the user to select from the following variants:

unity check,

section check,

stability check.
