| 摘 要： | 为研究采用喷射聚合物砂浆面层加固砖砌体墙的性能,应用有限元分析软件ABAQUS,对其进行非线性分析.首先利用大比例试件的试验结果对建立的墙体有限元模型进行对比验证,吻合良好.在此基础上,研究了加固面层厚度、聚合物砂浆强度对加固砖墙性能的影响,表明,当加固层较薄时,面层厚度的增大,使墙体承载力和变形能力的提高幅度大,而加固层较厚时则提高有所减缓；宜尽量采用强度较高的聚合物砂浆加固.

| Abstract: | In order to study the behavior of masonry wall stren gt hened with ejecting acrylic polymer mortar,finite element(FE) analysis software ABAQUS is used to carry out the nonlinear analysis.The result of large-scale specimens masonry walls agrees well with the FE models.On this basis,effects o f the thickness of the polymer mortar and its strength on the behavior of retrof itted walls are studied.The results show that,when the mortar cover is thin,t he load-carrying capacity and deformation ability of the wall... |
