摘　　要：利用空间结构分析设计软件MSTCAD对永昌县文化广场主题雕塑进行了结构整体分析。在没有建筑图纸的情况下,根据缩尺模型采用全站仪测量关键点坐标的方法建立了结构模型,为同类结构的建模提供了一种新的思路。通过对结构在风荷载及地震作用下的力学性能分析表明:结构振型比较复杂,在高阶振型之间存在耦合效应;结构整体变形较大,但可以满足正常使用要求;空间结构整体刚度大、稳定性好,是该类结构的首选结构方案。研究结果可以为该类复杂空间结构设计提供参考。The overall structure of the theme sculpture in Yongchang County Cultural Square was analyzed by MSTCAD,the spatial structure analysis and design software.In the absence of architectural drawings,the structure model was established by using the scale model and the method of measuring the coordinates of key points with the total station,which provided a new idea for the modeling of similar structures.The analysis of the mechanical properties of the structure under wind load and earthquake conditions shows that the vibration patterns of the structure are complex and there is coupling effect between the higher order vibration patterns.The overall deformation of the structure is great,but it can meet the requirements of normal use.The spatial structure with high stiffness and stability is the first choice for this kind of structure.The results can provide reference for the design of complex spatial structures.
