Experimental and numerical analysis on seismic behavior of exterior beam-column joints in recycled aggregate concrete f rame
摘要
Abstract
In order to realize the seismic behavior of recycled concrete exterior joints with different re‐placement ratio of gelled material ,an experimental study on two specimens of the recycled concrete ex‐terior joints was conducted under low‐cycle loading .The entire test process of all specimens and the fail‐ure mode were investigated ,and the hysteresis curves ,envelope curves and characteristic value ,degrada‐tion regulation of strength and stiffness were also carefully observed .The nonlinear finite element analy‐sis is made using the ABAQUS finite element package .The constitutive model of the recycled concrete is based on the constitutive model of the conventional concrete ,and modified according to the recycled con‐crete material test .The results of the nonlinear analysis for the recycled concrete exterior joints agree well with the specimens .It can be concluded that under cyclic loading using ABAQUS to simulate the node behavior is feasible .关键词
