南开大学大学生活动中心结构采用特殊的“扁担式”悬挑结构形式,分为张拉侧和悬臂侧,最大悬臂长度为22.75 m。施工工况分为立柱拆除临时支撑、立柱张拉以及胎架拆除,利用MIDAS有限元软件对施工各工况进行了数值模拟,并与现场监测采集的数据进行了对比分析。模拟计算理论值与实测数据吻合较好,验证了分析此类结构施工过程中有限元分析所采用的计算模型和方法的可行性,以确定结构在施工完成后能否达到设计要求的受力状态。
Nankai University Student Center activities using special structure “canopy ” cantilevered structure, divided into the tension side and cantilever side, the maximum cantilever length of 22.75 m. Construction conditions are divided into temporary support strut removal, column tension and removal of the tire rack, the use of MIDAS finite element software to simulate the construction conditions, and the scene monitoring data were collected for comparative analysis. The simulation theoretical value is in good agreement with the measured data, which verifies the feasibility of the calculation model and method used in the finite element analysis of the construction process of such structures to determine whether the structure can meet the design requirements of the force state after the construction is completed .
