This book represents a significant step toward a new contribution in the process of developing
the seismic vulnerability index. This is accomplished by releasing or reducing the role of the
rapid visual screening that is created by the opinions and decisions of experts which depend
on observations made while investigating the vulnerability damages caused by earthquakes.
Alternatively the computational analytical technique is preferable since it can be effective
in determining the seismic vulnerability index before the occurrence of an earthquake by
modeling the most affected influencing parameters that regulate the building performance. In
addition the seismic vulnerability index is supported by the vulnerability curves which
describe the probability of damages and are used to estimate the economic damage grade for each
building which is the topic of inquiry. In the end this helps to establish a clear vision and
sort of recommendations for engineers and specialists to follow in order to take into
consideration certain indices and factors before designing any specific structure. Because of
this the simplified work is utilized to manage and put into action measures that will protect
against the effects of seismic events before an earthquake really occurs. In addition to this
benefit the work that has been done is of significant assistance to the authorities that are
accountable for the restoration of the preexisting buildings and the cultural heritages.
