外包角钢短柱的性能分析与研究

Analysis and Research on the Behavior of Angle Steel Encased Concrete Short Columns

对影响外包角钢短柱强度与变形的因素进行了试验研究，探讨了砼轴压强度、纵向含钢率、配箍间距、箍筋直径对轴压短柱性能的影响，给出了轴压短柱承载力的计算公式，最后将外包角钢短柱与钢筋砼短柱进行了比较。

Experiments are studied on the angle steel encased concrete short columns,the influence factors of axial compressive strength,longitudinal steel ratio and stirrup spacing on the behavior are discussed and a formula of calculating limit bearing capacity is given. Compared with reinforced concrete short columns,it is found the behavior of angle steel encased concrete short columns is superior to that of reinforced concrete short columns.
