| dc.description.abstract | In spite of the advances of research in earthquake engineering in general and particularly on seismic design codes, catastrophic losses have occurred recently in many countries in the world, including countries in which earthquake engineering studies are priority tasks. It is clear that new developments in earthquake resistant design can only be applied to new projects, which represent a small part of the existing structures in a seismic area. This thesis work investigates seismic risk assessment of nine story building located in Addis Ababa City. ETABS software is used for non-linear static pushover analysis whereas Federal Emergency Management Agency (FEAM) earthquake loss estimation methodology is employed for earthquake loss estimation during risk assessment for the building model. Pushover analysis is used in order to investigate the capacity of the study building and from intersection of capacity curve and demand curve performance point of the building has been determined with this estimated performance value of the building probability of reaching or exceeding different damage state are calculated and finally with these probability of reaching or exceeding four different damage states the total loss due to structural damage becomes 1.585B birr The estimated value of economic losses based on the method FEMA-1999 approach obtained by MDP (mean damage probability) value of 18.09%. This means that the building has a small damage economic loss probability of 18.09% due to the expected earthquake scenario. And human life loss is calculated based on the assumption that 5 people dwell in single household. From the result it is observed that night time earthquake scenario causes high causality than day time scenario and rush hour scenario. And for particular time earthquake scenario the number of casualty decreases as level of severity increase. | en_US |
