摘    要:高强不锈钢绞线网-渗透性聚合砂浆加固法是一种新型加固工艺,它具有耐火、耐腐蚀、耐老化的优点。本文对6根 用该工艺加固的钢筋混凝土梁和1根对比梁进行了受弯性能试验研究。试验结果表明,该加固措施有效地提高了梁的受 弯承载力和刚度,较好地约束了裂缝的发展,具有良好的加固效果。在试验研究的基础上,本文给出了利用这种方法进行 加固的受弯承载力及刚度的设计计算公式,编制了计算机程序进行了理论分析,并给出了最大弯曲裂缝宽度的计算方 法。理论计算结果与试验结果吻合较好,可以满足实际工程设计的需要。

关 键 词:RC梁抗弯加固  高强不锈钢绞线网  渗透性聚合砂浆  试验研究

Abstract:Rehabilitation of RC members with stainless steel wire mesh and permeability polymer mortar is a new method of structural strengthening with the advantages of resistance to fire, corrosion and ageing. Experiments were conducted to investigate the flexural behavior of 6 strengthened RC beams and 1 comparative RC beam under different types of loadings. The experimental results showed that the flexural load-carrying capacity and stiffness were increased effectively and the propagation of cracks was reduced obviously by the rehabilitation. Based on the test results, the design formulae of flexural load-carrying capacity, stiffness and maximum crack width are proposed, and a computer analysis program is developed. The calculated results are in good agreement with the experimental ones. The calculation method proposed in this paper can be applied to the retrofit designs of RC structures.
Keywords:flexural strengthening of RC beams  stainless steel wire mesh  permeability polymer mortar  experimental study
