| 摘 要： | 为了更好地对高温作用后钢管混凝土的残余力学性能进行评估(特别是双向偏心构件的力学性能),为制订火灾作用后钢管混凝土的残余力学性能鉴定标准积累素材.笔者对恒高温作用后方钢管混凝土双向偏压构件的力学性能进行了15个试件的试验研究,设计了专用的双向偏心受压加载装置,并对影响构件残余力学性能的因素进行了试验分析.研究发现,高温后方钢管混凝土双向偏压构件仍有较高承载力,较好的延性,影响承载力的主要因素是温度.

| Abstract: | In order to assess the residual behavior of concrete filled steel tubes (CFST) after high temperature,especially biaxial eccentric compression members,some materials are provided to draw up the assessment codes of the residual behavior of CFST after fire.In this paper,fifteen square-CFST specimens after high constant temperature subjected to biaxial eccentric compression were carried out.Special set-up was also designed,and factors effecting on residual behaviour of members was also analysed.The results show that square CFST specimens subjected to biaxial eccentric compression have high bearing capacity and good ductility,and the factors effecting on bearing capacity are mainly temperature. |

| Keywords: | concrete filled square steel tubes constant high temperature biaxial eccentric compression bearing capacity |
