1. Steel Composite Girder Design to CSA-S6-14

Steel Composite Girder Bridge

Perform CSA-S6-14 code checks on straight or curved steel composite girder bridge with I-section, tub section and box section. (Beam element type only)

Account for short-term and long-term concrete properties using modular ratio (n) or time dependent material definition.

Analyze the construction sequence using construction stage analysis.

Check constructibility, strength (bending & shear resistance), serviceability, fatigue, shear connectors, transverse and longitudinal Stiffeners in tabular and excel format

View design forces or moments classified as Dead(Before Composite), Dead (After Composite) and Short Term loads in Design Force/Moment table.

View detailed design reports along with the formula used and their reference clauses from the code in the Excel report for all the design output positions chosen by the user.

5. Moving Load Optimization (AASHTO, BS, Eurocode)

Load > Moving Load > Traffic Line/Surface Lane > Moving Load Optimization

Load > Moving Load > Moving Load Cases

• In the previous versions, moving load analysis was used to find critical vehicle locations on bridges in the longitudinal direction. The critical locations of vehicles in the transverse direction

were determined by the user based on their experiences or trial-and-error approach.

• Now, Moving Load Optimization complements and extends the capabilities of moving load analysis and helps to significantly simplify the evaluation of critical vehicle locations. The critical

locations of vehicles will be identified in the transverse direction as well as longitudinal direction according to the code provision.

• It reduces the amount of time spent defining lanes and leads to more economical design.

• Other regional codes will be included in the next upgrades.

• The program will generate the centerlines of vehicles in the transverse direction within the carriageway width. • The spacing of the centerlines is defined by the user. (Anal. Lane Offset) • The first centerline will be generated at the centerline of carriageway. • The second centerline will be generated away from the first centerline by the value of "Anal. Lane Offset" to the both left and right side. • More centerlines will be generated by the user-defined spacing within the carriageway.

• Vehicle centerlines which do not satisfy the requirement of minimum spacing between vehicle and boundary of carriageway and minimum spacing between vehicles will be removed from the vehicle application. • For example, the three centerlines in the figure below will be removed from the vehicle application.

PSC > Design Parameter > Parameters > Eurocode 2-2:05

Shear at the interface between concrete cast at different times

In the previous version the β factor was taken conservatively as 1.0 for both positive moment and negative moment.

Now the factor is calculated as the ratio of the longitudinal force in the slab and the total longitudinal force in the compression zone for the positive moment and as the ratio of the longitudinal

force in the reinforcement and the total longitudinal force in the tension zone for the negative moment.

• In the previous versions, RSI wizard used to generate the multiple models and was applicable only for pre-processing. Now, as a post processing feature, RSI report generator could be used

to analyze all the models and obtain the compiled excel file.

• It reduces the time spent in report generation and provides the final summary sheet with checks based on UIC 774 - 3. These check limits could be manually modified for regional codes

• This wizard could only be used with Simplified Separate Analysis option. Report for Complete Analysis and other regional codes will be included in the next upgrades.

• The Report will contain tabulated data as well as graphical output for individual rail stresses, rail and deck relative displacements as well as deck absolute displacements.
