This book covers the seismic vulnerability assessment of unreinforced brick masonry (URBM) buildings. A method for seismic vulnerability assessment, based on the experimental results of series of URBM walls, is developed. The method produced satisfactory results when compared with the results of full-scale URBM buildings tested at various laboratories. The proposed method , although developed for URBM buildings, can also be applied to other types of masonry if the properties required to quantify the seismic performance are experimentally determined. The proposed method is used to assess the...
