摘　　要：为提出型钢混凝土构件的承载力计算的计算方法,选取实际工程案例中的一榀型钢混凝土组合框架,按照《建规》(GBJ 68-84)中的极限状态概率设计法进行设计并利用本文提出的容许应力法进行验算,确定最终截面设计。在ABAQUS有限元软件中建立型钢混凝土组合框架三维有限元实体模型,并施加对应设计荷载,进行有限元分析。根据计算结果可知本文提出的容许应力法的截面设计流程具有较好的合理性,可以有效计算型钢混凝土框架中混凝土、钢筋和型钢应力。In order to propose a calculation method for the bearing capacity of steel-concrete composite structure members,an actual engineering case was selected.In this paper,the design was performed in accordance with the limit state probability design method described in the building code(GBJ 68-84),checked using the proposed allowable stress method and then finalized the section.A three-dimensional finite element model of the steel-concrete composite frame was established in ABAQUS,corresponding design loads were applied and the finite element analysis was performed.The results indicate that the section design procedure according to the proposed allowable stress method is verified and this method can be used to calculate the stresses of concrete,reinforcement,and steel.
