高强钢绞线网-聚合物砂浆复合面层加固砖墙的试验研究

Test on Brick Walls Strengthened by Composite Cover of High Strength Wire Cable Mesh and Polymeric Mortar

高强钢绞线网聚合物砂浆复合面层具有高强、防火、聚合力强、无污染、施工简便等特点,是近年来国内外各类建筑加固补强工程所采用的新型应用技术。试验研究表明,对于混凝土构件,这种加固补强技术具有良好的效果。对采用该技术进行加固的15片砖墙的抗剪承载力试验进行了分析研究,结果表明,砖墙的抗剪承载力可以提高50%以上。该技术对于砌体构件同样具有良好的加固补强效果,可以在工程中应用。

The study on a new strengthening technique is presented for brick walls of the existing building. The composite cover combined with high strength wire cable mesh and polymeric mortar has been used to enhance the shear capacity of cracked walls. The results of laboratory test on 15 pieces of brick walls shows that such kind of strengthening materials and technique has featured good seismic performance and can be applied for engineering practices.
