Lad.Shanghai 200941 China) Abstract:Hydraulic synchronous sliding technology controlled by puter is extensively used in large- span spatial steel structure construction in recent years.Taking accumulated rotation sliding construction for steel roof of Shenzhen Universiade Sports Center Main Gymnasium as example the construction conditions for sliding and jig unloading are simulated and analyzed and the results show that during sliding the stress ratio of the most unfavorable bar is 0.375 and that is 0.682 during jig unloading and both of them can meet safety requirements.Moreover the calculation results and monitoring results are pared to indicate the accuracy of finite element simulation method.
