摘要:
 钢桁拱桥吊索塔架系统的受力在施工过程中非常重要。以江汉七桥为例，对该桥吊索塔架在不同施工阶段的力学性能进行有限元分析，利用Rhino+Grasshopper参数化建模建立钢桁拱桥和吊索塔架模型，基于Midas Civil有限元软件，在三种施工工况下，对吊索塔架整体结构的刚度、强度及稳定性进行计算分析。结果表明：相较于Midas Civil软件传统建模方式，利用参数化建模提升建模效率，减少了Midas建模前处理时间，利用Midas Civil分析得出相应的计算结果，为实际施工提供理论数据，具有一定的指导意义。
Abstract:
 The stress of suspension tower system of steel truss arch bridge is very important in the construction process. This paper takes Jianghan Qiqiao as an example. The mechanical properties of the suspender tower in different construction stages were analyzed by finite element method. Rhino+Grasshopper parameterized modeling was used to establish the model units of steel truss arch bridge and sling tower. Based on Midas Civil finite element software, the stiffness, strength and stability of the overall structure of the sling tower were calculated and analyzed under three construction conditions. The results show that compared with the traditional modeling method of Midas Civil software, parametric modeling can improve the modeling efficiency and reduce the pre-processing time of Midas modeling，and Midas Civil analysis is used to obtain the corresponding calculation results, providing theoretical data for the actual construction, which has certain guiding significance.
