钢筋混凝土结构分阶段相似模型试验设计研究
|
摘要
振动台模型试验大多采用缩尺模型进行试验,模型试验的依据是相似理论。目前钢筋混凝土模型试验依据的是弹性相似关系,没有考虑混凝土的非线性。本文依据混凝土材料在不同的变形阶段其割线模量的变化进行分阶段相似理论研究,并根据分阶段弹性模量的相似关系推出其它的相似关系,对钢筋混凝土结构分阶段相似模型试验设计进行了研究。
Most of shaking table model tests are carried out by using scale model,model tests are based on the similarity theory.Currently model tests of reinforced concrete are based on the elastic similarity relation, without considering the nonlinear of concrete.This article conduct a study on the phased similarity theory, based on the changes in the secant modulus at different deformation stages of concrete material,derive other similar relationships according to the similarity relation of the phased elastic modulus,and carry on research to the phased similar model experiment design of reinforced concrete structural.
