摘要
凤凰国际传媒中心钢结构为空间弯扭钢结构体系,钢结构体系支撑点较多、临时支撑分布范围广,运用通用有限元程序MIDAS对支撑的卸载顺序、卸载过程控制模拟分析,得出在卸载过程中监测点的位移变化,验证了"分区分步"的卸载原则,结果证明了该卸载方案是合理可行的。
The steel structure of Phoenix International Media Center is spatial bending and torsion steel structure.The steel structure system has many bracing points and large scope of temporary supports.The unloading sequences and unloading process controlling are simulated and analyzed by using the finite element software MIDAS.The analysis results show the displacement change of the monitoring points,validate the unloading principle of subarea with different steps and prove the unloading scheme feasible.
