68/02 DIETRICHTradeReady® Design Guide

http://www.dietrichmetalframing.com



A Glossary of terms:

Blocking: Solid block or piece of material placed between structural members to provide lateral bracing as in bridging and/or edge support for sheathing.

Bridging: Cross bracing or blocking placed between joists to provide lateral support.

C-Shape: A basic cold-formed steel shape used for structural framing members (such as joists). The name comes from the member’s "C" shaped cross-sectional configuration consisting of a web, flange and lip. It is also called a "C-section". Web depth measurements are taken to the outside of the flanges. Flange width measurements also use outside dimensions.

Clip Angle: An L-shaped short piece of metal (normally with a 90-degree bend) typically used for connections

Flange: The part of a C-Shape or track that is perpendicular to the web.

Flat Strap: Sheet steel cut to a specified width without any bends. Typically used for bracing andtransferring loads by tension.

Floor Joist: A horizontal structural framing member that supports floor loads.

Hard Side of Joist: Plane at joist along the web side opposite the C opening. The outside of the C.

Header: A horizontal built-up structural-framing member used for floor openings to transfer loads to adjacent framing members.

Joist Orientation: To assure that the holes line up across a given area of the foundation, the joist needs to be installed from the same beginning point.

Lip: The part of a C-Shape that extends from the flange at the open end. The lip increases the strength characteristics of the member and acts as a stiffener to the flange.

Loads, Live and Dead: Dead loads are the weight of the walls, partitions, framing, floors, ceilings, roofs, and all other permanent construction entering into and becoming a part of a building. Live loads are transient and sustained loads usually created by people and furnishing, respectively.

Multiple Span: The span made by a continuous member having intermediate supports.

Open side of Joist: Plane of joist along the flange of the open side of the "C".

Span: The clear horizontal distance between bearing supports.

Punchout: A hole or opening in the web of a steel-framing member allowing for the installation of plumbing, electrical, and other utility installation. A punchout may be made during the manufacturing process or in the field with a hand punch, hole saw, or other suitable tool.

Single Span: The span made by one continuous structural member without any intermediate supports.

Span Direction: The direction the joist lays across the foundation.

Structural Sheathing: The covering (e.g., plywood or oriented strand board) used directly over structuralmembers (e.g., joists) to distribute loads, provide lateral stability to the framing members, and generally strengthen the assembly.

Web: The part of a C-Shape or track that connects the two flanges.

Web Crippling: The localized permanent (inelastic) deformation of the web member subjected toconcentrated load or reaction at bearing supports.

Web Stiffener: Additional material that is attached to the web to strengthen the member against webcrippling. Also called a bearing or transverse stiffener.

*TradeReady® Steel Joist System (U.S. Patent# 6,301,854 and other Patents Pending)

Job Site Safety

Always follow OSHA guidelines and safety requirements when they are applicable.

• DO NOT walk on unbraced joist.Injury may result.

• DO NOT load floor decking before sheathing and bracing is complete.Place loads only over load bearing members.

• Wear work gloves to protect hands from cuts and injuries when working with steel.

• Safety goggles are recommended when cutting steel or when fastening members.

• Cutting and welding galvanized steel can produce harmful fumes that can be hazardous to health and causeirritation to respiratory system. Make sure all cutting and welding is done in a well-ventilated area.

• Use caution when working with steel when wet. Steel members may be slippery and cause injuries if notproperly handled.

Storage and Handling

Proper storage and handling will ensure the structural integrity of steel framing members and components

1. TradeReady® Steel joist bundles should be stored level.

2. DO NOT open bundles until time of installation. Use care when handling bundles and individualcomponents to prevent injury to handlers or damage by forklift or crane.

3. Twisting of steel joists, or applying loads to the joist when flat can damage the joist.Damaged steel joists should not be used.

4. Never handle steel joist flat. Beginning with the unloading process, and throughout all phases ofconstruction, care must be taken to avoid lateral and torsional bending of joists, which can cause damage to the steel joists.

Using This Design Guide

1. It is the responsibility of the user of the Design Guide for the DietrichTradeReady® Steel Joist System to identify:

Load conditionsLoad pathsBuildings general stabilityField Conditions

2. When designing a floor system, many factors may effect the end feelof the floor including:

Designed live and dead loads and deflection criteria.On center spacing of joist.Bridging and blocking.Floor sheathing type and size.Floor finish.Location of load bearing and non load bearing walls above and below.

3. Floor member selection may involve the following conditions for consideration:

Joist span.Joist web crippling.Joist attachment to girders or beams using Support clips.Rim and joist framing details.

4. Additional considerations may include:

TradeReady‚ rolled hole alignment and orientation.TradeReady‚ rolled hole access and field penetrations.

5. Value Engineering.

Often times the less expensive joist is a lighter gage joist combined with a taller web heightversus a heavier gage and shorter web height.

Excessive value engineering (choosing the least expensive member for every framing area) may hinder the ordering and framing process by creating too many custom parts and pieces for the construction process. Utilizing only one or two different joist sizes is recommended.

Maximum Spans



TradeReady® Steel Joist Span Tables are to be utilized in conjunction with the notes below.

Span Table Notes:

1.) Spans are based on continuous lateral support of the compression flange.

2.) Web crippling capacity is based on a minimum bearing length of 3.5". The minimum available TradeReady® rim track thickness is used.

3.) Recommended bridging is 8'0" on center maximum.

4.) Fy is 33 ksi for 18 gauge, 50 ksi for 16,14, and 12 gauge.

5.) If an additional point load is located @ the end bearings (e.g. from a wall above), web crippling must be checked separately.

Using This Design Guide

1. It is the responsibility of the user of the Design Guide for the DietrichTradeReady® Steel Joist System to identify:

Load conditionsLoad pathsBuildings general stabilityField Conditions

2. When designing a floor system, many factors may effect the end feelof the floor including:

Designed live and dead loads and deflection criteria.On center spacing of joist.Bridging and blocking.Floor sheathing type and size.Floor finish.Location of load bearing and non load bearing walls above and below.

3. Floor member selection may involve the following conditions for consideration:

Joist span.Joist web crippling.Joist attachment to girders or beams using Support clips.Rim and joist framing details.

4. Additional considerations may include:

TradeReady‚ rolled hole alignment and orientation.TradeReady‚ rolled hole access and field penetrations.

5. Value Engineering.

Often times the less expensive joist is a lighter gage joist combined with a taller web heightversus a heavier gage and shorter web height.

Excessive value engineering (choosing the least expensive member for every framing area) may hinder the ordering and framing process by creating too many custom parts and pieces for the construction process. Utilizing only one or two different joist sizes is recommended.

*TradeReady® Steel Joist System (U.S. Patent# 6,301,854 and other Patents Pending)

Job Site Safety

Always follow OSHA guidelines and safety requirements when they are applicable.

• DO NOT walk on unbraced joist.Injury may result.

• DO NOT load floor decking before sheathing and bracing is complete.Place loads only over load bearing members.

• Wear work gloves to protect hands from cuts and injuries when working with steel.

• Safety goggles are recommended when cutting steel or when fastening members.

• Cutting and welding galvanized steel can produce harmful fumes that can be hazardous to health and causeirritation to respiratory system. Make sure all cutting and welding is done in a well-ventilated area.

• Use caution when working with steel when wet. Steel members may be slippery and cause injuries if notproperly handled.

Storage and Handling

Proper storage and handling will ensure the structural integrity of steel framing members and components

1. TradeReady® Steel joist bundles should be stored level.

2. DO NOT open bundles until time of installation. Use care when handling bundles and individualcomponents to prevent injury to handlers or damage by forklift or crane.

3. Twisting of steel joists, or applying loads to the joist when flat can damage the joist.Damaged steel joists should not be used.

4. Never handle steel joist flat. Beginning with the unloading process, and throughout all phases ofconstruction, care must be taken to avoid lateral and torsional bending of joists, which can cause damage to the steel joists.

5.4



A Glossary of terms:

Blocking: Solid block or piece of material placed between structural members to provide lateral bracing as in bridging and/or edge support for sheathing.

Bridging: Cross bracing or blocking placed between joists to provide lateral support.

C-Shape: A basic cold-formed steel shape used for structural framing members (such as joists). The name comes from the member’s "C" shaped cross-sectional configuration consisting of a web, flange and lip. It is also called a "C-section". Web depth measurements are taken to the outside of the flanges. Flange width measurements also use outside dimensions.

Clip Angle: An L-shaped short piece of metal (normally with a 90-degree bend) typically used for connections

Flange: The part of a C-Shape or track that is perpendicular to the web.

Flat Strap: Sheet steel cut to a specified width without any bends. Typically used for bracing andtransferring loads by tension.

Floor Joist: A horizontal structural framing member that supports floor loads.

Hard Side of Joist: Plane at joist along the web side opposite the C opening. The outside of the C.

Header: A horizontal built-up structural-framing member used for floor openings to transfer loads to adjacent framing members.

Joist Orientation: To assure that the holes line up across a given area of the foundation, the joist needs to be installed from the same beginning point.

Lip: The part of a C-Shape that extends from the flange at the open end. The lip increases the strength characteristics of the member and acts as a stiffener to the flange.

Loads, Live and Dead: Dead loads are the weight of the walls, partitions, framing, floors, ceilings, roofs, and all other permanent construction entering into and becoming a part of a building. Live loads are transient and sustained loads usually created by people and furnishing, respectively.

Multiple Span: The span made by a continuous member having intermediate supports.

Open side of Joist: Plane of joist along the flange of the open side of the "C".

Span: The clear horizontal distance between bearing supports.

Punchout: A hole or opening in the web of a steel-framing member allowing for the installation of plumbing, electrical, and other utility installation. A punchout may be made during the manufacturing process or in the field with a hand punch, hole saw, or other suitable tool.

Single Span: The span made by one continuous structural member without any intermediate supports.

Span Direction: The direction the joist lays across the foundation.

Structural Sheathing: The covering (e.g., plywood or oriented strand board) used directly over structuralmembers (e.g., joists) to distribute loads, provide lateral stability to the framing members, and generally strengthen the assembly.

Web: The part of a C-Shape or track that connects the two flanges.

Web Crippling: The localized permanent (inelastic) deformation of the web member subjected toconcentrated load or reaction at bearing supports.

Web Stiffener: Additional material that is attached to the web to strengthen the member against webcrippling. Also called a bearing or transverse stiffener.
