【摘要】 高强钢绞线网-聚合物砂浆加固法是一种新型的加固方法,它具有耐火、耐腐蚀、耐老化的优点。本文通过有限元模拟,对钢筋混凝土梁的抗剪加固进行非线性全过程分析。分析结果表明,通过合理的建立有限元模型,可以较好的模拟高强钢绞线网-聚合物砂浆加固混凝土梁的受剪性能。分析结果和试验结果均表明高强钢绞线网-聚合物砂浆加固法可有效提高抗剪刚度、开裂荷载、极限承载力,验证了用ANSYS进行有限元分析的可行性和优越性。更多还原

【Abstract】 Rehabilitation of RC members with high-strength wire mesh and polymer mortar is a new method of structural strengthening with the advantage of resistance to fire,corrosion and ageing.The finite element method(FEM) for evaluating the nonlinear analysis of the shear behavior of RC members strengthened with high-strength wire mesh and polymer mortar is presented in this paper.The analytical results show that FEM could effectively simulate the shear behavior of the repaired members with the proper numerical model.The analytical and experimental results indicate that the strengthening method is effective in increasing the shear stiffness,cracking load and ultimate capacity and validate the feasibility and advantage of the FEM analysis using ANSYS.更多还原
