摘要
从众多约束混凝土应力-应变规律模型中优选出其中四种,部分改造并添加了滞回关系,将其分别加到基于纤维模型梁柱单元的三维空间框架非线性动力反应分析程序中,最后以R.Park等人的低周反复荷载下压弯柱的试验为校准基础,主要从构件层次进行了模拟、比较,分析了各种混凝土应力-应变关系模型中不同的骨线线取法和滞回规律取法对钢筋混凝土柱性能模拟效果的影响。
In this paper, four models are selected as the representatives and applied to nonlinear dynamic analysis program for space frames which is based on the beam -column elements using the finite element flexibility method and the fiber model. Park＇s test on combined axial and bending colurmns under cyclic loading are taken as the calibrations, comparisons to material and structural member level are drawn and the analytical results of various models are discussed.
