Abstract

When a seismic load is applied horizontally or laterally on unreinforced masonry walls (URM), the walls behave in two different ways, viz., in-plane (IP) and out-of-plane (OoP). This review beneficially provides a literature overview of the most cited research papers on Scopus, and the database is evaluated with VOSviewer software for scientometric analysis. This review paper delves into the practical applications of various types of reinforcement for masonry walls, specifically focusing on four commonly used systems: externally bonded strengthening techniques using fiber-reinforced polymers (FRP), steel-reinforced grout (SRG), fabric-reinforced cementitious mortar (FRCM), and textile-reinforced mortars (TRM). The main objective of the paper is to explore the efficacy of these reinforcement techniques in strengthening masonry walls, and to provide a comprehensive overview of their respective advantages and limitations. A further detailed study of the extent of the literature is performed about the effect of the different strengthening systems on the mechanical properties of different categories of masonry walls like a cement block, stone, and clay brick are described and categorized. The efficiency of OoP strengthening can depend on various factors, such as the types of masonry units, the rendering mortar, the type of strengthening system, the bond between the different materials interfaces, the geometry of the wall, and the loading conditions. By utilizing the practical method of Dematel (Decision-making trial and evaluation laboratory) analysis, this review can delve deeply into the impact of various factors and precisely identify the crucial components of the cause-and-effect connection. The results indicate that the bond between material interfaces is the critical factor. This meticulous and structured review offers valuable perspectives for researchers and engineers, showcasing current research trends and presenting potential avenues for future exploration.

未加筋砌体墙面外加固技术综述

当地震荷载水平或横向施加在无筋砌体墙(URM)上时，墙体表现为两种不同的方式，即面内(IP)和面外(OoP)。本文综述了Scopus上被引次数最多的研究论文，并使用VOSviewer软件对数据库进行了科学计量分析。这篇综述论文深入探讨了各种类型的砌体墙加固的实际应用，特别关注四种常用的系统:外部粘结加固技术，使用纤维增强聚合物(FRP)，钢增强浆液(SRG)，织物增强水泥砂浆(FRCM)和纺织增强砂浆(TRM)。本文的主要目的是探讨这些加固技术在加固砌体墙方面的效果，并对各自的优点和局限性进行全面的概述。对不同强化体系对不同类别砖石墙(如水泥块、石材和粘土砖)机械性能的影响进行了进一步的详细研究，并对其进行了描述和分类。面向对象加固的效率取决于各种因素，如砌体单元的类型、渲染砂浆、加固系统的类型、不同材料界面之间的粘结、墙壁的几何形状和加载条件。通过运用Dematel (Decision-making trial and evaluation laboratory，决策试验与评价实验室)分析的实用方法，本综述可以深入挖掘各种因素的影响，准确识别因果关系的关键组成部分。结果表明，材料界面间的结合是影响材料性能的关键因素。这篇细致而有组织的综述为研究人员和工程师提供了有价值的观点，展示了当前的研究趋势，并为未来的探索提供了潜在的途径。

期刊介绍： Fibers (ISSN 2079-6439) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications on the materials science and all other empirical and theoretical studies of fibers, providing a forum for integrating fiber research across many disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. The following topics are relevant and within the scope of this journal: -textile fibers -natural fibers and biological microfibrils -metallic fibers -optic fibers -carbon fibers -silicon carbide fibers -fiberglass -mineral fibers -cellulose fibers -polymer fibers -microfibers, nanofibers and nanotubes -new processing methods for fibers -chemistry of fiber materials -physical properties of fibers -exposure to and toxicology of fibers -biokinetics of fibers -the diversity of fiber origins
