Unreinforced masonry (URM) is used in a number of structures including buildings, bridges, driveways, parking areas, manufacturing plants, blast furnaces, mining appurtenances and fencing. Unfortunately, due to missed maintenance and lack of durability in materials themselves, many masonry structures are rapidly deteriorating and are rendered unsafe. To worsen the situation, recent earthquakes have demonstrated that URM structures perform poorly under seismic conditions. The existing repair and strengthening technique are unfortunately neither cost-effective nor sustainable and perform unsatisfactorily. Much further research is required in this area.

无筋砌体（URM）用于许多结构，包括建筑物，桥梁，车道，停车场，制造厂，高炉，采矿附属设施和围栏。 不幸的是，由于缺乏维护和材料本身缺乏耐久性，许多砌体结构正在迅速恶化，并变得不安全。更糟糕的是，最近的地震表明，URM结构在地震条件下表现不佳。遗憾的是，现有的修复和加固技术既不具有成本效益，也不可持续，并且表现不令人满意。在这一领域还需要进行更多的研究。
