摘要
以某火车站无站台柱雨棚改造施工项目为例,基于有限元程序ANSYS,对改造前后结构在静力荷载与地震作用下的响应进行了有限元数值模拟。分析结构在静力荷载与地震作用下的受力性能,并将数值模拟结果与监测数据进行对比,验证了ANSYS在分析雨棚结构受力性能方面的可行性,为火车站改造前后大跨钢结构雨棚的力学性能理论分析与优化设计提供参考。
Taking a reconstruction project of a no platform column canopy of a railway station as an example,based on the finite element software ANSYS,finite element numerical analysis is conducted to the structure before and after reconstruction under static load and earthquake action. The performance of the structure under static load and earthquake is analyzed,and the numerical simulation results are compared with the monitoring data. To verify the feasibility of ANSYS in the analysis of canopy structure stress performance,which provides a reference of theoretical analysis and optimal design of mechanical properties of the train station's large span steel structure canopy.
