The objective of this report is to provide the background work for the development of recommended seismic design provisions for steel deck diaphragms utilizing ASCE 41 / AISC 342. The current (2017) edition of ASCE 41 for ...

The standing seam roof (SSR) system is the most commonly used roof system for metal buildings due to its superior durability, water tightness, and energy efficiency. In this type of system, SSR panels attach to Z-shaped ...

Building archetypes are fundamental to exploring and demonstrating the seismic behavior of modern structures. No suitable archetypes or prototypes exist in the open literature that focus on steel deck diaphragms for ...

Compared to vertical elements of a building’s seismic force resisting systems, our understanding of the horizontal elements, i.e. the diaphragms, is grossly lacking. Recent research showed that diaphragm design forces that ...

This report provides a summary of nonlinear response history analyses conducted on a three- dimensional model of a series of steel buildings with special concentric braced frames (SCBFs). The models are conducted in OpenSees ...

Diaphragms are the floor or roof structures in a building that transfer lateral load horizontally to the braced frames or shear walls. For many types of buildings, the building code requires semirigid diaphragm analysis ...

In structural analysis of building structures, the in-plane stiffness diaphragms is needed so that lateral loads will be properly distributed to elements of the lateral-force resisting system. In US building codes, diaphragm ...
