【摘要】 采用数值方法计算了考虑钢管初应力影响时的中空夹层钢管混凝土压弯构件荷载-变形关系曲线.在此基础上,分析钢管初应力系数、构件长细比、截面含钢率、荷载偏心率、材料强度和空心率等因素的影响规律,最终建议了考虑钢管初应力影响时中空夹层钢管混凝土压弯构件承载力影响系数的实用验算方法.更多还原

【Abstract】 An attempt to predict the load-deformation behavior of concrete-filled double skin steel tubular beam-columns with the effects of initial stress is carried theoretically.Based on the theoretical model,influ- ence of the initial stress Coefficient,slenderness ratio,sectional steel ratio,load eccentricity ratio,strength of the materials,as well as hollow section ratio are discussed.Finally,formulas for the influence coefficient of bearing capacity of concrete-filled double skin steel tubular beam-columns considered the effects of initial stress are suggested.更多还原
