摘要:
为研究高强冷弯矩形截面钢管混凝土柱(CFST)在偏心受压荷载作用下的力学性能,对Q420型高强冷弯钢设计制作的矩形截面钢管混凝土柱进行偏心受压试验,获得试件在偏压荷载作用下的破坏形态、跨中挠度及应变分布规律,并分析不同参数对试件偏心受压承载能力的影响.试验结果表明:高强冷弯矩形截面钢管混凝土柱的偏心受压性能受长细比、偏心率和宽厚比等参数影响较为明显,长细比、偏心率和宽厚比越大,高强冷弯矩形截面钢管混凝土柱的偏心受压承载能力越小.
Abstract:
In order to investigate the mechanical performance of high-strength cold-deformed rectangular-section concrete-filled steel tubular(CFST)columns under eccentric compression loading, the specimens were designed and manufactured using Q420 high-strength cold-formed steel, the eccentric compression experiments were conducted to obtain the failure mode, mid-span deflection, strain distribution. The effects of different parameters on the eccentric compressive bearing capacity of the specimens were investigated. The experimental results show that: the eccentrically-compressed performance of high strength cold-formed rectangular-section CFST columns is significantly affected by the slenderness ratio, eccentricity ratio and width-thickness ratio. As the slenderness ratio, eccentricity ratio and width-thickness ratio increase, the eccentric compressive bear-ing capacity of high strength cold-formed rectangular section CFST columns decreases.
