    摘要:

    砖石作为建筑材料在世界范围内广泛使用,由砖石和砂浆组成的砌体结构抗拉、抗剪强度较低,抗震性能不足,地震作用下容易破坏甚至倒塌,需要进行补强加固以改善砌体结构的力学性能。纤维增强复合材料(fiber reinforced polymer,FRP)由于抗拉强度高、重量轻、安装方便和耐腐蚀等优势在砌体结构加固领域有广泛的应用前景;内嵌FRP(near-surface mounted FRP,简称NSM-FRP)加固由于对结构的重量和外观影响很小,在历史砌体建筑加固方面更有优势。本文总结了国内外学者对NSM-FRP加固砌体结构这一技术的相关研究进展,并对NSM-FRP加固砌体结构的发展进行了展望。

    Abstract:

    Brick and stone are widely used as building material in the world. Masonry structure composed of brick, stone and mortar has low tensile and shear strength, insufficient seismic resistance, and is prone to damage or even collapse under earthquake action. Therefore, strengthening is needed to improve the mechanical properties of masonry structure. Due to high tensile strength, light weight, easy installation and corrosion resistance, fibre reinforced polymer(FRP) has been widely used to strengthen the masonry structure. Near surface mounted FRP(NSM-FRP) has more advantages in strengthening historic masonry buildings because it has little influence on the weight and appearance of the structures. In this paper, the research progress of masonry structures strengthened with NSM-FRP is summarized, and the development of masonry structures strengthened with NSM-FRP is prospected.
