摘　　要：通过建立空间网架有限元分析模型,对某实例网架结构杆件的受力进行了计算分析,研究了杆件的受力特点和分布规律.对网架结构施工中常出现的问题进行了总结,在此基础上,根据理论计算结果,基于杆件的受力特点,提出有针对性地进行网架结构的施工质量控制思路,保证了结构施工质量,监测结果表明网架结构的应力和整体变形满足相关规范的要求.With establishing the finite element analysis model of space truss, the force analysis of the space truss membres were worked on, the force characters and distributing law of members were researched. Based on summarizing the normal problems in the course of construction, according to the comptue results, a quality control method of the space trusss construction was brought up,which take into account the force characters,and the construction quality was ensured. The measure data indicate that the stress and deformation of the space truss satisfy the code requires.
