简要地介绍了断裂力学理论在混凝土领域中的应用 ,结合混凝土 、 复合型裂纹断裂准则 ,并考虑混凝土梁中受拉钢筋对 K1 c的影响 ,分析了影响无腹筋钢筋混凝土梁受剪承载力的因素。
The application of fracture mechanics theory in concrete is briefly introduced. Combined with the criterion of fracture of composite concrete and composite crack, the influence of tensile reinforcement on K1c in concrete beam is considered, and the influence of shear strength of reinforced concrete beam without reinforcing rib factor.
