静载试验在空间网壳结构中的应用

Application of static load test in space net-shell structure

通过对结构模型的理论计算,在局部加载作用下,采用静载试验方式,根据杆件应力比基本等效的原则,对壳体结构中部分杆件的应力和杆件节点位移进行了检测和研究。对比分析试验结果可知,该试验结果与结构模型计算结果的线性关系基本一致,进而对该工程项目的结构安全性能进行了评定。

Based on the theoretical calculation of structural model and the principle of basic equivalence of stress ratio of members,the static load test method is adopted to detect and study the stress and displacement of some members in shell structure.By comparing and analyzing the test results,the linear relationship between the test results and the calculation results of structural model is basically the same.According to this,the work is carried out.The structural safety performance of the project is evaluated.
