Disasters
are natural phenomena which cannot be prevented. However, their negative
effects on living creatures can be reduced. After a destructive earthquake, the
situation in the disaster-affected area should be defined as soon as possible.
The later it is defined, the more the number of victims and economical losses
can be increased. One of the most important defining processes is the damage
evaluation of earthquake affected buildings. After a destructive earthquake, in
many cases, some residents who continue to live in damaged houses are under
high risk. Many victims can be injured or lost their lives in damaged buildings
because of aftershocks. On the other hand, some residents who live in
seismically safe enough buildings from an engineering point of view abandon
their buildings. Nowadays, some post-earthquake damage assessment methodologies
are used all over the world. These methodologies still have some problems in
terms of time, objectiveness, methodological problems, reliability, etc. In
last twenty years some important applications of post-earthquake damage
assessment were experienced especially in the aftermath of the 1995
Hanshin-Awaji and the 2011 Great East Japan Earthquakes, in Japan. These
experiences clearly revealed that the more reliable, objective and faster
methodology is needed for post-earthquake damage assessment. In order to solve
these problems mentioned above, the researches on the real-time post-earthquake
residual seismic capacity evaluation system have started to develop a new
methodology in recent fifteen years. In this thesis, the author studied to
determine the damage on a target building because of the 2011 Tohoku Earthquake
by applying the commonly used system identification methods and a part of the
new methodology being developed in the limited time.
