纤维编织网增强水泥基材料加固砌体结构研究进展

State-of-the-art review on strengthening masonry structures with fabric-reinforced cementitious matrix

砌体结构在地震等自然灾害中具有较大的易损性,加固是提高其安全性的有效方法之一。纤维编织网增强水泥基材料(FRCM)具有优良的力学性能,作为加固材料具有对原结构自重增加较小、几乎不影响建筑物使用功能、施工便捷以及与砌体材料协同受力性好等优点,且可以较好地应用于砌体古建筑的加固修复,在砌体结构加固领域具有广泛的应用前景。基于近年来国内外已开展的研究工作,主要从FRCM与砌体界面黏结性能、FRCM加固砌体构件/结构力学性能两个方面系统介绍相关的研究进展,并由此提出一些可以继续深入研究的问题。

Masonry structures are vulnerable in natural disasters like earthquake actions,and it is one of the effective methods to strengthen them to improve the security.As a kind of strengthening material,fabric-reinforced cementitious matrix(FRCM)has good mechanical properties,such as less increase in original structural weight,little influence on the use function of buildings,easy of construction and good compatibility with masonry substrate.FRCM can also be well used for the strengthening and retrofitting of heritage buildings.Therefore,FRCM has extensive and good application prospect in the field of strengthening masonry structures.Based on the research works in recent years at home and board,the relevant research progress is systematically introduced from the point of interfacial bond properties between FRCM and masonry substrate and the mechanical performance of FRCM strengthening masonry members or structures.In the end,some problems that needed to be further researched are proposed based on the present research status.
