HRB500级钢筋约束混凝土轴压力学性能

摘要

For the study about compression performance of HRB500 level stirrup constrained concrete column, using fin-ite element software to simulate axial compression of the rei-nforced concrete column, and the result shows that the com-pression performance of the specimens is improved with the increase of volume stirrup ratio. In addition, HRB500 level steel bar does not yield when the specimen reaches the limit stress, and stirrup stress is the largest at the midpoint along the middle cross-section side length.%为研究HRB500级箍筋约束混凝土柱的受压性能，采用有限元软件对该类钢筋混凝土柱进行了轴心受压模拟。结果表明，试件的受压性能随体积配箍率增加得到改善；HRB500级钢筋在试件极限应力时并未屈服，高度中间截面边长中点处箍筋应力最大。
