摘　　要：在新型全预制装配框架体系中,斜企口梁是重要的受力构件。为了获得斜企口梁的极限承载力,应用剪切摩擦和拉压杆模型等理论,对刚性企口连接斜企口梁在复杂受力状态下的多种破坏形式给予分析,推导出相应的极限承载力公式,并通过已有的试验数据对承载力理论计算值进行验证。结果表明,该极限承载力公式具有较高精度。The oblique match-beams are the vital supporting members in a new-type full precast concrete frame structure.In order to obtain the ultimate bearing capacity of oblique match-beams with rigid scarf joint,various failure modes were analyzed with shear-friction theory and strut-and-tie model method,and corresponding design formulas for the ultimate strength were deduced.At last,through the existing experimental data,theoretical calculations on the bearing capacity of the oblique match-beams were verified.The results show that the ultimate bearing capacity formula with high accuracy.
