摘要

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.
