The manual includes pertinent design information considerations fastener information deck shear capacity tables and a plethora of highly relevant design examples stepping you through all the.

Roof deck diaphragm design example. The sdi diaphragm design manual third edition is an excellent design reference every engineer should utilize if designing with steel deck diaphragms. First off the roof diaphragm design example is an extremely basic direct and utilitarian design every single current trademark. The roof deck is a wr wide rib type panel with a panel width of 36. The roof structure consists of a panelized hybrid roof system which is very common in large diaphragm roofs in the seismically active western united states.

A roof design gives the chance to extra floor space in the roof volume similar to a space or upper room space. The sdi diaphragm design manual third edition is an excellent design reference every engineer should utilize if designing with steel deck diaphragms. The manual includes pertinent design information considerations fastener information deck shear capacity tables and a plethora of highly relevant design examples stepping you through all the. And a width b 300 ft.

Main features roof diaphragm design example. Design the diaphragm for wind loading using allowable stress design method. Figure 1 illustrates the basic concept for a roof and wall diaphragm. The roof acting as a simple span horizontal girder of depth b distributes the wind line load as a shear reaction along the top of the end walls perpendicular to l.

This example illustrates the design of a large flexible diaphragm in a big box retail store subjected to lateral seismic loading. Now let s work on an example. Design a roof deck for a length of l 500 ft. The roof deck is supported by joists that are thick and spaced at 5 ft.
