| 摘 要： | 提出钢筋混凝土裂缝开展角计算公式和钢筋混凝土裂缝角软化桁架模型。这种模型满足二维应力平衡条件、莫尔应变协调条件和混凝土双轴软化本构关系。它不仅能预估钢筋混凝土的强度，特别是开裂后的剪切强度，而且能表达荷载—变形非线性关系的全过程。

| Abstract: | The formula of crack angle and the crack angle softened truss model of reinforced concrete membrane elements are presented in this paper.The model satisfies the two dimensional stress equilibrium,Mohr's cricular strain compatibility and softened biaxial constitutive laws of concrete.This model not noly predicts the ultimate strength of reinforced concrete,but also provides the entire load deformation history. |
