抽象。本研究评估了无钢筋砌体建筑物的抗震能力与选定的模板设计建造每前现代规范在阿尔巴尼亚考虑砌体的非线性行为。三个住宅楼与模板设计被选中代表位于阿尔巴尼亚地震区的中等城市的住宅楼的重要比例。模板设计的建筑物和材料属性的选择是基于档案和现场调查在阿尔巴尼亚的几个城市。通过在两个主要方向上进行的推覆分析确定了所调查建筑物的承载力曲线。这些建筑物的抗震性能已被确定为各种地震级别。根据FEMA（联邦应急管理局）440指南进行抗震能力评估。过去的地震中建筑物损坏的原因进行检查，使用的调查建筑物的能力评估的结果。结果表明，除一栋外，其余采用模板设计的住宅建筑均远不能满足要求的性能标准。此外，不足之处和可能的解决方案，以提高被调查的建筑物的能力进行了讨论。
Abstract. This study evaluates seismic capacity of the unreinforced masonry buildings with the selected template designs constructed per pre-modern code in Albania considering nonlinear behaviour of masonry. Three residential buildings with template designs were selected to represent an important percentage of residential buildings in medium-size cities located in seismic regions of Albania. Selection of template designed buildings and material properties were based on archive and site survey in several cities of Albania. Capacity curves of investigated buildings were determined by pushover analyses conducted in two principal directions. The seismic performances of these buildings have been determined for various earthquake levels. Seismic capacity evaluation was carried out in accordance with FEMA (Federal Emergency Management Agency) 440 guidelines. Reasons for building damages in past earthquakes are examined using the results of capacity assessment of investigated buildings. It is concluded that of the residential buildings with the template design, with the exception of one, are far from satisfying required performance criteria. Furthermore, deficiencies and possible solutions to improve the capacity of investigated buildings are discussed.
