印度大部分地区容易发生大地震，过去的地震已经揭示了与无钢筋砌体（URM）和钢筋混凝土（RC）框架结构不当相关的脆弱性。URM结构在地震多发地区存在严重的危险。非工程钢筋混凝土结构可能导致毁灭性的后果。经济较弱部门和低收入群体的家庭的住房无疑是这类事件的挑战。无论居住在城市还是乡村，每个人都希望有一个砖石墙和钢筋混凝土屋顶的房子，就像大城市地区的建筑一样。约束砌体结构（CM）是一种在许多国家流行的建筑体系，可以满足社会的这一需求。虽然CM建筑是非正式开始的，但在几次破坏性地震中，抗震性能确实很好。这种类型的建筑结合了URM和RC结构的优点，并且不需要RC建筑所需的复杂性。本文利用以往的抗震性能和文献资料，对URM、填充RC框架和CM结构的地震反应进行了比较。它的结论是，约束砌体是一个更好的选择，在印度地震多发地区的可持续住房。
Much of India is prone to substantial earthquakes, and vulnerability associated with both unreinforced masonry (URM) and improperly built reinforced concrete (RC) frame constructions has been unmasked by past earthquakes. URM structures present a severe hazard in earthquake-prone regions. And non-engineered RC structures can lead to devastating consequences. Housing for families in the economically weaker sector and the lower-income group is undoubtedly challenging to such events. Regardless of residing in a city or village, everyone desires a house with masonry walls and RC roof, just like the buildings in larger urban areas. Confined masonry (CM) construction, which is a popular building system in many countries, can fulfil this need of society. Though CM building started informally, the seismic performance is found to be really well in several destructive earthquakes. This type of construction combines the advantages of URM and RC structures and does not need sophistication required in RC construction. In this paper, the seismic response of URM, infilled RC frame and CM buildings is compared using past seismic performance and literature. It is concluded that confined masonry is a better alternative for sustainable housing in seismic-prone regions of India.
