Abstract

Despite the increase in population and earthquake-prone areas, our country makes good use of insurance coverage to compensate for earthquake damage, which is one of the
Common solutions in the world are neglected, as well as insurance companies, offering premium rates regardless of type of structure and seismic response.
Therefore, it is necessary to examine the response of existing buildings to earthquake to calculate the ultimate earthquake insurance rate. in this research
Obtained from nonlinear dynamic analysis; indexes of drift, hardness, and plastic joint damage, as well as for items such as ritual-
Letter, quality of materials, seismic hazard level, number of structural floors, a separate correction coefficient calculated using Delphi method and these coefficients and
Damage indices are multiplied together and the final rate is presented as "Earthquake Engineering Certificate" with a rate of 0.206 obtained from
The rates used in insurance companies that operate without instrumental analysis have been more accurately obtained. Accordingly premium
Earthquake for one year for the 7-storey steel building examined, from 270 thousand tomans) Premium of the structure examined by the insurance companies (to
The amount has decreased by 202 thousand tomans. Conversely, when calculating this rate for earthquake-resistant structures, this coefficient is definitely higher
It will be the premium used by insurance companies so in fact based on this research, each structure is based on its own vulnerability to earthquake,
The premium will pay.
