不同结构的振动台试验模型等效设计方法

为解决在钢筋混凝土结构、钢结构的振动台试验模型中，相似理论与实际模型设计之间的差异问题，以实现对原型结构合理模拟进行的研究，针对不同材料结构按构件等效设计的原则，分别得到钢筋混凝土结构、钢结构模型的设计计算公式，并给出计算实例，以指导振动台试验模型设计。

Shaking Table Test Model Design in Different Structures

Scaled model is more widely used with the popularity of the shaking table around the world.In shaking table test,model design principle is so various with the type of tested structure that different methods were proposed in this paper.The stress scale factor difference between concrete and steel has to be considered into the model design for reinforced concrete(RC) structures,while for steel structures,the key point lies in the non-reduced scale of the steel material.Based on the similitude theory and member equivalent principle,shaking table model design formula was deduced in this paper for RC structures and steel structures,respectively.Examples were given to show the application of the formula.
