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。
為研究HRB500級箍觔約束混凝土柱的受壓性能，採用有限元軟件對該類鋼觔混凝土柱進行瞭軸心受壓模擬。結果錶明，試件的受壓性能隨體積配箍率增加得到改善；HRB500級鋼觔在試件極限應力時併未屈服，高度中間截麵邊長中點處箍觔應力最大。

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.
