Damage Assessment of Structures due to the 2006 Java Tsunami

The paper describes damage assessment of structural components such as wall and column in a masonry infilled house due to a tsunami, assessing the damage data of structures in the south coast of Java due to the 2006 Giant Earthquake and Tsunami. The effect of wave loads with failure mode of subject structural components was verified, inversely computing the dominant parameter ‘α’ representing the amplification of tsunami wave pressure against a structural component. It was found that its crack mode might occur when parameter α takes the value ranging from 4 to 5, and that major failure mode such as collapse or shear crack might occur although parameter a takes more than 3 dependent upon tsunami affection.
