Dynamic Stability Analysis of Big Span Steel Tubular Truss

Article Preview

Abstract:

An arch-truss roof structure with circular steel tube is applied to a gymnasium. Natural frequency and modes of this overall roof structure are analyzed, and time-procedure analysis is acted by applying ANSYS software. The analysis results demonstrate that this roof structure has larger stiffness, and its maximum node displacement under earthquake(7 degrees)can meet the requirements.
