摘要:
为研究内配螺旋箍筋方钢管超高强混凝土柱的偏压受力性能,对2个内配螺旋箍筋方钢管混凝土柱和1个普通方钢管混凝土柱进行偏心受压试验,试件内填混凝土的轴心抗压强度为111 MPa.结果表明:组合柱承载力的下降主要是由混凝土压溃导致;螺旋箍筋对提高组合柱承载力的作用不明显,但可显著提高组合柱的延性.
Abstract:
Two spiral-confined concrete-filled steel tube(CFST)columns and one concrete-filled steel tube column with the concrete compressive strength of 111 MPa were tested under eccentric axial loading to investigate the behavior of eccentrically loaded square spiral-confined high-strength concrete-filled steel tube columns. The results indicate that concrete crushing is the main cause for the loss of the load-carrying capacity of composite columns;the spiral stirrup does not effectively increase the load-carrying capacity of composite columns, but it can significantly improve the ductility of composite columns.
