摘要
采用量纲分析法和动力方程法,推导了动力试验模型在任意配重条件下与原型结构的动力相似关系,并介绍了在弹性及弹塑性阶段,如何应用得出的相似关系由模型的试验结果推算原型的动力性能。以两个底部框架砖房1/6 比例模型在不同配重条件下的振动台试验结果及动力分析结果的比较分析。
The analogical ratio between scale models with less ballast and their prototypes under shaking table test are provided by the dimensional analysis and differential equation methods,and it is recommended that the elastic as well as the elastoplastic behavior of the prototypes can be evaluated from the shaking table test of the scale models with less ballast based on the analogical ratio between them at the corresponding stage. The results of the shaking table test and numerical analysis of two 1/6 scale models of masonry building with frame structure at lower stories are given in order to verify the correctness of the suggested analogical ratio in the paper.
