| 摘 要： | 分析了钢筋混凝土简支短梁和连续短梁受力特征的异同，提出了集中荷载作用下钢筋混凝土连续短粱受剪承载力计算的组合桁架模型（combined truss model），该计算模型考虑了斜裂缝出现后混凝土应力一应变软化的特性，满足平衡方程和协调方程．根据该模型，推导了混凝土连续短梁受剪承载力的理论计算公式，理论计算结果与所收集到的试验结果符合较好．

| Abstract: | The similarities and differences of mechanical properties between R. C. short beams with simple supports and continuous short beams are analysed. The combined truss model is presented to analyse the shear capacity of R. C. continuous short beams subjected to concentrated load. The equilibrium, compatibility conditions and the softened stress - strain relation of the main strut are considered. According to the model, the calculation formulas are deduced. The theoretical predictions are in good agreement with the test results. |
