Concrete On Metal Deck Diaphragm Design

In building design these loads are typically caused by wind and seismic events although earth and water can exert lateral forces as well.

Concrete on metal deck diaphragm design.

Specimens failing in the diagonal tension mode 42. Expansion joint design information. The steel deck diaphragm calculator has two parts to it. Test facility 17 3 3.

It is usually constructed of wood sheathing steel deck or concrete. With profis df diaphragm software you can quickly select fasteners sidelap screws and other components and then calculate diaphragm shear and other variables to find the best solution for your application. A rectangular uninterrupted plane a diaphragm behaves primarily as if it were a short deep beam figure 1. In some cases however the concrete fill is not structural.

Expansion joints in buildings. Steel deck diaphragms 12 2 4. Calculate your unfilled deck diaphragm shear and stiffness for your exact condition based on the steel deck institute diaphragm design manual third edition ddm03. Just as the floor or roof is checked for vertical load capacity it is considered a diaphragm in the plane of the floor and check for shear when designing the lateral force resisting system.

Let the technical specialists at hilti prepare a steel roof deck or concrete. It may be a topping slab or an insulating layer that is used to encase conduits or provide a level wearing surface. A rectangular uninterrupted plane a diaphragm behaves primarily as if it were a short deep beam figure 1. Fasteners 15 experimental investigation 17 3 1.

Test parameters 28 3 6. Optimized solutions and diaphragm capacity tables optimized solutions is a designer s tool and it offers optimized design solutions based on cost and labor for a given shear and uplift. In building design these loads are typically caused by wind and seismic events although earth and water can exert lateral forces as well. Steel deck plywood and concrete are all common materials utilized in diaphragm applications.

In its most basic form i e. Profis df diaphragm design software. Displacement program 24 3 5. General behavior and failure modes 29 3 6 1.

Steel deck plywood and concrete are all common materials utilized in diaphragm applications. Steel deck reinforced concrete diaphragms 9 2 3. The diaphragm can be thought of as a horizontal beam or as a plate element.
