圆钢管混凝土轴压中长柱的承载力
|
摘要
首先应用模型柱法,对钢管混凝土轴压中长柱荷载-变形关系进行全过程分析,得到了钢管混凝土轴压中长柱承载力的数值解法;其次,根据切线模量法推导了钢管混凝土轴压中长柱稳定承载力计算公式;再次,基于模型柱法,探讨了构件长细比、混凝土强度等级、含钢率和钢材屈服强度对钢管混凝土轴压中长柱承载力稳定系数的影响,并在修正切线模量法推导的计算公式的基础上,建立了钢管混凝土轴压中长柱承载力实用计算公式;最后将该公式计算结果与各国216根钢管混凝土轴压中长柱承载力有效试验结果进行了对比。结果表明:该承载力计算公式所得结果与试验结果吻合较好,且偏于安全。
Firstly,based on fiber model method,load-deformation relation of middle long concrete-filled circular steel tubular columns under axial loading was simulated.The numerical calculation method of bearing capacity of middle long columns was developed.Secondly,according to the tangent modulus method,the calculation formulas of stability bearing capacity of middle long column were presented.Thirdly,applying fiber model method,the influences of the significant parameters,such as slenderness ratio,strength grade of concrete,yield strength of steel and steel ratio of cross-section on stable coefficients of middle long columns were discussed and a practical calculation formula of stability bearing capacity for the columns was established through modifying the formulas by tangent modulus method.Finally,calculation results of the formula were compared with bearing capacity effective test results of 216 middle long concrete-filled circular steel tubular column at home and abroad.Results show that the calculated results of calculation formula of the bearing capacity which agree well with test results are in safe range.
