Lad.Shenshen Guangdong 518040 China) Abstract:The roof of main stadium in Shenzhen Universiade Sports Center is a single-layer folded-surface spatial grid system.Based on the engineering characteristics structure members are assembled on temporary support jigs before it could resist its gravity and other load when members integrated.The reasonable construction scheme is proposed by condition analysis and unloading maneuverability. Monitoring basis is provided by finite element simulation analysis and the solution of the key problems of unloading are introduced.The results show that the monitoring results are consistent with theoretical analysis results.
