Concrete On Metal Deck Diaphragm Design

In some cases however the concrete fill is not structural.

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. Expansion joint design information. In cases with structural concrete fill the metal deck is considered to be a concrete form and the diaphragm is treated as a reinforced concrete diaphragm. Expansion joints in buildings.

In its most basic form i e. Steel deck plywood and concrete are all common materials utilized in diaphragm applications. 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. Specimens failing in the diagonal tension mode 42.

Steel deck diaphragms 12 2 4. Let the technical specialists at hilti prepare a steel roof deck or concrete. 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 its most basic form i e.

The diaphragm can be thought of as a horizontal beam or as a plate element. The steel deck diaphragm calculator has two parts to it. It may be a topping slab or an insulating layer that is used to encase conduits or provide a level wearing surface. Test parameters 28 3 6.

Fasteners 15 experimental investigation 17 3 1. It is usually constructed of wood sheathing steel deck or concrete. In building design these loads are typically caused by wind and seismic events although earth and water can exert lateral forces as well. A rectangular uninterrupted plane a diaphragm behaves primarily as if it were a short deep beam figure 1.

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. Calculate your unfilled deck diaphragm shear and stiffness for your exact condition based on the steel deck institute diaphragm design manual third edition ddm03. Vulcraft floor deck design tools. General behavior and failure modes 29 3 6 1.

A rectangular uninterrupted plane a diaphragm behaves primarily as if it were a short deep beam figure 1. Test facility 17 3 3. Displacement program 24 3 5.
