【摘要】 本文在钢筋混凝土剪扭构件软化桁架理论基础上,合理地考虑剪跨比、预应力等因素影响,并在较大剪跨比时引入截面平面假设,建立了斜截面开裂后梁剪跨区加载变形的全过程分析法,以求解构件抗剪强度。28片模型试验梁抗剪强度实测值,与本文建立的方法所计算的理论值符合良好。更多还原

【Abstract】 On the basis of the softening truss theory for concretemembers subjected to shearing and tortion, taking into proper account theeffects of the shear span-depth ratio, prestressing force etc. and intro-ducing the plane section assumption for larger shear span-depth ratios,we establish a whole--course approach to analysing the loading defor-mation within the shearing region of RC/PC beams with inclinedcracking. Reasonable agreement has been achieved between the shearingstrengths measured from 28 model beams and those predicted with theapproach proposed.更多还原
