摘要
根据型钢混凝土构件的受力性能及典型破坏形态 ,从力的传递和扩散角度对型钢混凝土构件的横向配箍率、纵向钢筋的最小直径进行了定量分析 ,并根据板的弹塑性稳定理论 ,对型钢混凝土构件受压区混凝土保护层最小厚度进行了理论分析和公式推导 ,同时从混凝土保护层开裂的角度 ,根据力扩散原理 ,建立了型钢混凝土临界保护层厚度的计算方法 ,并对两种计算方法的计算结果进行了分析比较 .
In this paper, according to the mechanical performance and typical shear bond failure models of steel reinforced concrete members, and based on the force transfer and pervasion principles, the minimum ratio of transverse hoops, the minimum diameter requirement of longitudinal reinforced bars and the minimum thickness of concrete cover were quantitatively analyzed. By applying the board elastoplastic stability theory, the minimum concrete cover requirements of steel reinforced concrete beams and columns were analyzed in details, and the calculation method as well as a series of calculation formula were established. All these may be helpful to the designation and experiment research of steel reinforced concrete structures.
