Load-Bearing Experiment and Theoretical Analysis of a Large-Scale Space Truss

本文阐述了一大型空间网架的现场载荷试验,确定是否符合承载力检验标准,对结构进行安全鉴定。通过试验验证ANSYS分析软件模拟载荷条件下的结构变形特点的可行性,分析结构的可靠性。试验与理论相结合是网架安全检测中一种较合理的方法。

The paper presents the process of the load-bearing experiment on a large-scale space truss in-site, which is for ensuring the structure to meet load-bearing capacity requirement specified in relevant code and conduct the safety appraisal. The structural deformation characteristics under load is simulated by ANSYS software and validated through the experiment. It is demonstrated that the method combining computer-simulation and laboratory testing is a resonable way in safety inspection for space truss.
