Development of Steel Deck Diaphragm Seismic Design Provisions for ASCE 41/AISC 342
(2019-01-04)
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 ...
Experimental Study on the in-plane behavior of standing seam roof assembly and its use in lateral bracing of rafters
(2020-01)
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 ...
SDII Building Archetype Design v2.0
(2019-12-16)
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 ...
Seismic Behavior of Steel BRBF Buildings Including Consideration of Diaphragm Inelasticity
(2020-03, r)
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 ...
Seismic Behavior of Steel SCBF Buildings Including Consideration of Diaphragm Inelasticity
(2021-04)
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 ...
Cantilever Testing of Concrete-Filled Steel Deck Composite Diaphragms Using Various Types of Steel Reinforcing
(2021-11)
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 ...
Semirigid Diaphragm Analysis of Archetype Floor Using Design Office Models
(2022-05)
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 ...
Stiffness of Concrete-Filled Steel Deck Diaphragms
(2022-01)
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 ...
