相似理论在混凝土结构振动台模型设计中的应用

运用相似理论介绍混凝土结构振动台试验模型设计的全过程,总结出了一种通用的设计方法,并且用似量纲分析方法给出了各相似常数的一般计算公式,将该方法运用到实际地震模拟振动台试验中,比较部分实测结果与原型理论计算结果的对应情况,发现二者吻合良好,于是该设计思路是切实可行的。

Similarity Theory And Concrete Structure Model Design of Shaking Table Test

This paper provides a practical method on designing concrete structural model of shaking table test based on similarity theory. And a quasi-dimentional analysis method is adopted to solve almost all similar constants, In model designing several basic similar constants are defined at first and oher main similar constants are obtained according to the basic similar constants. This method is applied in practical earthquake simulated shaking table test, Partial results are compared with the theoretical calculation result. The experimental result is in concordance to the theoretical calculation result, So the practical designing method is feasible.
