FRP加固砌体墙体结构技术理论研究与应用

Theory research and application of FRP reinforced masonry wall technology

FRP加固技术目前是国际土木工程领域研究开发的一个热点,其不仅可以适用于加固砌体构件的局部开裂;并且可以用于承载力不足的砌体加固。综合现阶段国内外纤维增强复合材料FRP加固砌体结构的研究,系统地介绍了FRP材料近年来加固、修复、改善砌体结构的技术和应用,较全面介绍了FRP的性能、FRP加固技术的优势和施工工艺。研究成果表明,FRP加固砌体结构可以有效地改善砌体的破坏机理和受力性能,改善砌体结构的抗震受剪承载力和变形性能,有效地将砌体的脆性破坏形态转化为其他破坏形态。

This paper simply introduces the applications of FRP reinforced masonry structure repair technology,thecomprehensive performance and the advantages of FRP reinforcement technique of FRP.In addition,this paper intro?duces the scholars at home and abroad in recent years,the development and application of FRP composite masonrystructure reinforcement of experiment and theoretical study,which mainly includes shear capacity of FRP reinforcedmasonry structure,seismic and out-of-plane bending performance,and the bond performance of FRP and masonrystructure is reviewed.The research shows that FRP reinforcement can improve the shear of masonry structure andplane bending ultimate bearing capacity,also improves the seismic performance of structure,avoids due to the brittlefailure of brick masonry structure of the whole structure of sudden destruction.
