Ld.Kunming Yunnan 650224 China) Abstract:The steel roof of Qujing Stadium is a large-span suspended pipe truss structure.The structure was assembled into segments hoisted outside the plan and closed in the air.The impact of process can't be neglected so the erection process was simulated and analyzed by SAP2000.Simulation on every installation step of plan truss agrees with actual situation.The result shows that the stress ratio of most members is between 0 and 0.1.The“X"structure unit is relatively independent to each other.The low temperature in winter has little influence on the construction.
