Abstract
This thesis is conducted to investigate the effects of December 19, 2010 and November
24, 2011 earthquakes in Hosanna town. Due to the limitation of the available data only
seven buildings were selected for the investigation. The paper examines the five
buildings by qualitative analysis and two of buildings, both qualitative and quantitative
studies.
The qualitative method was based on the damage evaluation method using FEMA and
EMS. The results of the qualitative evaluation of buildings show that the damages were
mainly non-structural and minor structural damages. The quantitative study of the two
buildings was performed by using pushover analysis with SAP2000 software as per
ATC-40 life safety performance criteria. Results of case study 01 showed that some
structural members of building are heavily damaged, whereas the structural members of
case study 02 building are in the safe range. Therefore, in order to sustain future
earthquake some of the structural members of case study 01 need to be strengthened.
