Only few data are available on seismic performance of these buildings at present. Therefore, in this paper, the researchers conducted study and survey relevant for these buildings. The following activities were taken place.
1. Collecting and analyzing seismic records observed around the area concerned as well as evaluating input
motion characteristics for the subject area.
2. Field survey was conducted to understand the damage situation caused by series of earthquakes. Then consider the relationship between the damage trends and the various influencing factors.
