| 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。文中用简化的软化桁架模型对钢筋混凝土梁柱内节点进行抗剪强度分析,提出了用简化的软化桁架模型设计钢筋混凝土梁柱内节点的步骤。同时,通过对一个钢筋混凝土梁柱内节点的验算,证明了所提出模型的有效性和可行性。

| Abstract: | The simplified softened strut-and-fie model originates from the strut-and-fie concept and satisfies equilibrium, compatibility, and the constitutive laws of cracked reinforced concrete. The shear strength of interior RC beam-column joints is analyzed by the simplified softened strut-and-tie model in this paper. The steps are proposed for designing interior RC beam-column joints with simplified softened strut-and-tie model. An example is used to test the validity of the method. The result shows that the simplified softened strut-and-tie model is useful and available. |
