张弦桁架结构预应力拉索施工过程仿真分析

Simulation analysis of prestressed lasso construction process of tensioned truss structure

为了解张弦桁架结构在预应力拉索施工过程中的受力和变形状态,本文以某大型会展中心工程为例,采用Midas Gen有限元软件进行仿真分析,得出张弦桁架结构构件的应力、位移及拉索索力,并与实际施工过程中构件的应力、位移、拉索索力进行对比。结果表明:施工过程仿真分析能保证施工过程的安全性,对制定施工方案和指导实际施工具有一定的参考价值。

In order to understand the stress and deformation state of tensioned truss structure during prestressed lasso construction, a large exhibition center project is taken as an example and Midas Gen finite element software is used for simulation analysis to derive the stress, displacement and cable force of lasso, and to compare with the stress, displacement and cable force of lasso of the components in the actual construction process.The results show that the simulation analysis of the construction process can ensure the safety of the construction process, and have certain reference value for formulating the construction plan and guiding the actual construction.
