PROPOSED METHOD FOR COST ASSESSMENT OF SEISMIC MITIGATION DESIGNS FOR REINFORCED CONCRETE BUILDINGS

Abstract

The analysis methods used to design the structures to resist earthquake load ranges from equivalent linear static analysis to nonlinear dynamic analysis.Each seismic mitigation design for the structure influence its life cycle cost that includes the construction cost and repairing cost after earthquake damage.It is necessary to perform a cost assessment for each seismic mitigation design to know the effective design on the building life cycle cost. The methodology followed in this study provides initial guidelines to assess the cost associated with usinga variety of design methodsfor reinforced concretestructures, developing a performance based analysis to get the weakness points in the structure after earthquake, select the retrofitting strategies that would be indicated to repair the structure after the earthquake, and to assess the results founded from each design method or different design codes.
