摘　　要：张弦立体桁架结构在大跨度空间结构中有着广泛的应用。一个成功的张弦立体桁架结构设计方案需要经过多次计算及优化。而长期以来对该类问题的求解一般是通过开发相应的有限元程序来完成,但是开发程序需要大量的人力、物力,开发周期长,程序代码的利用率低。基于ANSYS的二次开发语言APDL和UIDL,编制张弦空间立体桁架计算程序,为结构工程师和研究人员对空间立体桁架的受力性能和结构优化分析进行进一步研究提供依据和参考模型,以提高科研和设计的工作效率。The prestressed spatial truss string structures have been widely used in large span spatial structures.A successful design scheme of a prestressed spatial truss string needs several times of calculation and optimization.However,the solutions of the problems are generally obtained through the development of the corresponding finite element programs for a long time,but the development process requires a lot of manpower and material resources with a long cycle and low utilization of program code.Based on ANSYS secondary developed languages APDL and UIDL can prepare calculation program of prestressed spatial truss,which provides a basis and model for structural engineers and researchers to study the structure further to improve the efficiency of scientific research and design.
