Concrete On Metal Deck Diaphragm Design

A rectangular uninterrupted plane a diaphragm behaves primarily as if it were a short deep beam figure 1.

Concrete on metal deck diaphragm design.

The diaphragm can be thought of as a horizontal beam or as a plate element. Specimens failing in the diagonal tension mode 42. Expansion joints in buildings. Expansion joint design information.

The steel deck diaphragm calculator has two parts to it. A rectangular uninterrupted plane a diaphragm behaves primarily as if it were a short deep beam figure 1. In building design these loads are typically caused by wind and seismic events although earth and water can exert lateral forces as well. In some cases however the concrete fill is not structural.

In its most basic form i e. Displacement program 24 3 5. Vulcraft floor deck design tools. 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.

It is usually constructed of wood sheathing steel deck or concrete. General behavior and failure modes 29 3 6 1. 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. Steel deck plywood and concrete are all common materials utilized in diaphragm applications.

Let the technical specialists at hilti prepare a steel roof deck or concrete. Test parameters 28 3 6. Steel deck plywood and concrete are all common materials utilized in diaphragm applications. 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. In its most basic form i e. Fasteners 15 experimental investigation 17 3 1. Profis df diaphragm design software.

Steel deck reinforced concrete diaphragms 9 2 3. Steel deck diaphragms 12 2 4. 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.
