摘要：设计制作了5根配置矩形螺旋箍筋的混凝土短柱和3根配置普通箍筋的混凝土短柱，研究了混凝土强度、箍筋间距对构件极限承载力、力学性能的影响，在试验的基础上，利用ANSYS有限元软件对混凝土短柱进行了静力非线性分析。结果表明：与普通箍筋混凝土短柱相比，矩形螺旋箍筋混凝土短柱的极限承载力和抗变形能力有所提高；箍筋间距越小，其对混凝土短柱的约束效果越好；混凝土强度等级越高，构件的极限承载力越大；有限元分析结果与试验结果基本一致。 Abstract: Five concrete short columns with rectangular spiral stirrups and three concrete short columns with ordinary stirrups were designed, and the effects of concrete strength and stirrup spacing on the ultimate bearing capacity and mechanical properties of concrete short columns were studied. Based on the test, the static nonlinear analysis of concrete short columns was carried out by using ANSYS finite element software. The results show that compared with concrete short columns with ordinary stirrups, the ultimate bearing capacity and anti deformation capacity of concrete short columns with rectangular spiral stirrups are improved. The smaller the stirrup spacing, the better the restraint effect. The higher the concrete strength grade, the greater the ultimate bearing capacity. The analysis results are basically consistent with the test results.

The smaller the stirrup spacing, the better the restraint effect. The higher the concrete strength grade, the greater the ultimate bearing capacity. The analysis results are basically consistent with the test results.
