摘要

摘要: 为研究型钢再生混凝土短柱的抗剪性能，推广再生混凝土结构的工程应用，基于OpenSees软件，采用弯剪相互作用的位移型梁柱单元并利用纤维截面建模，对8根型钢再生混凝土短柱在低周反复荷载作用下的抗剪性能进行数值模拟。对比分析再生粗骨料取代率、轴压比以及体积配箍率的变化对型钢再生混凝土短柱抗剪性能的影响规律。结果表明：再生粗骨料取代率为100%的型钢再生混凝土短柱与普通型钢混凝土短柱的抗剪性能接近；轴压比和体积配箍率对型钢再生混凝土短柱的抗剪性能有较大影响；基于OpenSees软件能够模拟型钢再生混凝土短柱在压、弯、剪共同作用下的非线性反应。

Abstract: In order to study the shear behavior of the steel recycled aggregate concrete short columns and popularize the application of recycled concrete in engineering, the numerical simulations of the shear behavior of 8 steel recycled aggregate concrete short columns under low-cyclic reversed loading were carried out by OpenSees Program based on the flexure-shear interaction displacement-based beam-column element and fiber section.The influence regularity of recycled aggregate replacement ratio, axial compression ratio and volumetric stirrup ratio on the shear behavior of the steel recycled aggregate concrete short columns was analyzed.The results indicate that the shear behavior of steel recycled aggregate concrete short columns is close to that of the steel reinforced concrete short columns, and axial compression ratio and volumetric stirrup ratio have a obvious influence on the shear behavior of the steel recycled aggregate concrete short columns.Non-linear response of the steel recycled aggregate concrete short columns under the combination of compression, bending and shearing action can be simulated by means of OpenSees Program.
