In this paper , based on the test results of reinforced concrete deep beams , short beams and slender beams under flexture , the behavior and the ultimate moment of deep flexture members are discussed in detail . the calculating formulas for flexture bearing capacity and the design suggestion of reinforeed concrete deep flexural members are also given , and this may provide reference for the revision of p . r . c . design code 结合我国混凝土结构设计规范修订的需要，根据我国深梁、短梁专题组的试验结果，较详细地分析了深受弯构件力臂变化的规律，提出了可与浅梁衔接的钢筋混凝土深受弯构件的受弯承载力计算公式，为我国混凝土结构设计规范的修订补充这方面的内容提供了依据

According to the above formula , the initial rigidity and ultimate moment is calculated by developed program to several kinds of gabled frames end - plate connection joint with different types ( such as end - plate connection horizontally placed , vertically placed and inclinedly placed ) , different end - plate thickness , different bolt diameter . the different result is compared with different end - plate thickness , the different force arm in joints , different bolt diameters and strength grades 按推导的公式编程计算了不同形式(端板外伸式、端板平齐式、端板斜接、柱腹板加劲) 、不同端板厚度、不同螺栓直径的门式刚架梁柱端板节点的初始刚度、节点极限弯矩，并比较了不同端板厚度、不同节点力臂、不同螺栓直径和强度等级、不同连接形式下初始刚度和极限弯矩的变化。
