【摘要】 结构模型的振动台试验是研究工程结构抗震性能的重要方法,正确处理模型与原型的相似关系以及由模型反应正确推导原型反应是很重要的问题。本文以某3层框架结构为原型,对其进行了模型设计,并且运用有限元分析程序对原型和模型进行了地震作用下的动力分析,由模型结果按照相似关系推出原型反应并将其与计算值进行了比较,从而研究了模型与原型的相似关系,给出了相关公式。更多还原

【Abstract】 Vibroplatform test is an important method to study seismic performance of engineering structure.Processing the similarity relation and deducing response of original mold correctly are very important.This paper took one three-story frame building as original mold,designed a test model,used finite element program to do dynamical analysis under seismic action,and deduced response of original mold,them compared with calculation result.Finally the similarity relation was studied,the formulas were given.更多还原
