Research on the stability of suspen-dome with stacked arch structure in Chiping Gymnasium

A new structural system, suspen-dome with stacked arch structure, is accepted in Chiping Gymnasium, and it consists of a suspen-dome and two spatial arches. Due to the existence of two spatial arches, the stability behavior of suspen-dome with stacked arch structure is different from general suspen-dome structure. In this paper, the stability of suspen-dome with stacked arch is analyzed using general finite element software package ANSYS, and the main work of the paper are as following: 1) the over view of Chiping Gymnasium is firstly introduced; 2) it is discussed that the effect of existence of the two arches on the stability; 3) the stability analysis of the steel roof of Chiping Gymnasium under condition that the hoop cables can slide around the bottom strut joints is discussed.
