石砌建筑在阿尔卑斯-喜马拉雅地震带的许多地区很常见，它们在最近的地震中的倒塌已导致许多人死亡。贫困和缺乏替代品阻碍了用更具延展性的材料取代砌石，但通过结合木材或增强砂浆的水平连接可以大大降低无筋砌石的脆性。作为与安卡拉土耳其地震研究所联合研究项目的一部分，研究农村地震防护的低成本升级策略，对全尺寸墙体构件进行了静态侧向荷载测试和脉冲台上的动态测试。基于墙体倾覆的简单“屈服线分析”被证明能够对静态试验中的失效模式和失效载荷进行有用的预测，并为动态试验中未加固和加固墙的相对性能提供指导。这些测试的结果用于评估土耳其东部农村建筑升级的大规模计划的成本效益。
Stone masonry buildings are common in many areas in the Alpine-Himalayan earthquake zone, and their failure in recent earthquakes has been the cause of many deaths. Poverty and lack of alternatives prevent the replacement of stone masonry with more ductile materials, but the brittleness of unreinforced stone masonry can be considerably reduced by the incorporation of horizontal lacings of timber or reinforced mortar.As part of a joint research project with the Turkish Earthquake Research Institute in Ankara to study low-cost upgrading strategies for rural earthquake protection, full-scale wall elements were subjected to static lateral loading test and dynamic tests on an impulse table. A simple ‘yield-line analysis’ based on wall overturning was shown to be able to give a useful prediction of the mode of failure and failure load in the static test, and give guidance on the relative performance of unreinforced and reinforced walls in the dynamic test. The results of these tests were used to assess the cost-effectiveness of a large-scale programme of upgrading rural buildings in eastern Turkey.
