| 摘 要： | 通过对不同工况下三跨两层平面框架结构的检测实验,对比分析了恒载对框架结构动力检测参数的影响问题,得出了恒载对一般框架结构的检测刚度和检测频率有较大影响的结论,建议在多层框架结构的新建设计以及实测鉴定中也应考虑重力二阶效应的影响.

| Abstract: | According to a test on lateral stiffness and frequency of a earthquake-resistant designed RC frame structure under different work conditions, this paper analyzed the influence of deadweight to testing stiffness of RC frame structure and come to the conclusion that the influence of deadweight to the testing stiffness of normal frame strueture can not be ignored. We suggest that Gravity second-order effect should be taken into account in structure design and structure test and assess of multilayer frame structure. |
