摘　　要：简化的软化桁架模型源于拉压杆的概念,满足带裂缝混凝土的平衡条件、相容条件和本构关系,阐述简化的软化桁架模型的传力途径、设计步骤等.影响钢筋混凝土短肢剪力墙的因素较多,为了分析短肢剪力墙的抗剪强度,分别应用软化桁架模型法、现行规范方法计算短肢剪力墙的抗剪承载力,同时与试验结果加以比较.软化桁架模型法可以估算短肢剪力墙抗剪承载力,并且比现行规范方法准确.验证了所提出简化的软化桁架模型的有效性、实用性.A simplified softened truss model originates from the strut-tie concept and satisfies equilibrium,compatibility and the constitutive laws of cracked reinforced concrete,expound transitive path and design procedure of the simplified softened truss model.Because many factor affect shear strength of RC short-limbed shear walls,the softened truss model and method of code are used to calculate shear strength of RC short-limbed shear walls and compare with the experimental results.The softened-truss model could calculate shear strength of RC short-limbed shear walls and more accurate than the method of code.The simplified softened truss model is reformed and utilized.
