在认真学习框架柱双向受剪承载力计算方法“超强系数法”的基础上 ,提出目前正在修订的 2 0 0 0《混凝土结构设计规范》(征求意见稿 )中采用该方法的条文规定尚存在着不足之处 ,并提出了解决该问题的建议。同时本文作者提出了双向受剪承载力的三折线简化计算方法 ,对简化计算方法的误差进行了分析。最后给出了两种计算方法的设计与校核示例。
On the basis of careful study of the method of calculating the ultimate bearing capacity of frame columns by “super-coefficient method”, the provisions of the “Design Code for Concrete Structures” (Draft for Consultation 2000) There are shortcomings, and put forward suggestions to solve the problem. At the same time, the authors proposed a simplified method to calculate the triaxial line of the two-way shear capacity, and analyzed the error of the simplified method. Finally, two examples of calculation methods are given.
