Diaphragm truss method
WebBuilders should consider installing the following: Install steel connectors, strapping, or screws at roof-to-wall connections to increase the uplift resistance along the load path. Secure roof sheathing to rafters or trusses using dense screw patterns, clips, and straps to increase the uplift resistance. WebAug 8, 2024 · The Seismic Design Category will be used for redundancy factor ρ in calculating diaphragm design forces. Fundamental Period of the Structure T The fundamental period of a structure can be determined from the modal analysis of the structure. ASCE 7-16 allows the approximation of the fundamental period of a structure …

WebIllinois Department of Transportation WebOct 19, 2024 · There are two basic approaches for consideration of accidental torsion in a response spectrum analysis (RSA). 1. The first approach uses the "Static Procedure". A torsional moment (Mz) is computed based on the seismic lateral story force obtained from RSA which is multiplied by the specified diaphragm eccentricity.
