摘　　要：对某会展中心钢桁架的施工过程进行数值模拟分析和监控。针对制定的钢桁架施工方案,采用MIDAS/GEN软件进行施工全过程数值模拟分析,以确保方案的可行性;同时对施工过程钢桁架的变形和关键受力部位的应力进行监测,以保证结构在施工过程中的安全,并验证数值模拟的准确性。测试结果表明:本工程数值模拟准确,施工方案可行,卸载后结构处于安全状态。The whole construction process of steel truss of a exhibition center is simulated and monitored. According to the construction scheme of steel truss, MIDAS/GEN software was used to carry out numerical simulation analysis of the whole process of construction, in order to ensure the feasibility of the scheme. In the same time, the deformation of the steel truss and the stress of the key parts in the constructional process were monitored, in order to ensure the safety of the structure. Also, the accuracy of numerical simulation was verified. The test results show that the numerical simulation is accurate, the construction scheme is feasible, and the structure is in a safe state after unloading.
