Abstract

An arch-truss roof structure with circular steel tube is applied to a gymnasium, which is supported by two three-dimensional trusses with square steel tubular, and the connections between arch-truss and spatial truss are set to hinged supports. 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 can meet the requirements.
