Abstract

The authors investigated bunding damage conditions in five areas of Galle, Matara, and Hambantota, Sri Lanka affected by the 2004 Indian Ocean Tsunami. This paper presents tsunami vulnerability functions for the buildings, a relationship between building damage and inundation, in the country In order to develop the functions, 1,535 bunding damage data in terms of structural types, solid (mainly reinforced concrete) and non-solid (masonry and timber-frame), and inundation height data of 153 points obtained by the field survey and contour models were examined. The developed fragility curves clearly show structural vulnerability differences, and it will be useful for damage estimation to reduce tsunami related damage in the country in the future.
