摘要
研究了高温后圆形、方形、矩形截面钢管混凝土轴压构件力学性能的差异 ,并对其高温后残余承载力的计算方法及承载力降低系数进行了探讨·研究发现 ,圆形截面的钢管混凝土在遭受高温作用后的残余承载力降低最多 ,矩形截面的次之 ,方形截面的降低最少·
The difference among the mechanical behavior of circular, square and rectangular CFST members subjected to axial compression was studied. The calculation method of the remained load bearing capacity and the reduction factor of load bearing capacity were also discussed. The remained load bearing capacity decreases slightly for square section, but heavily for circular section. The load bearing capacity decreases moderately for rectangular section.
