Abstract:
Evaluation of seismic performance of existing buildings is vital to reduce their seismic
vulnerability. Performance can be evaluated by the interaction between structure's capacity and the
probable seismic demands. After the evaluation, suitable retrofitting methods can be used to enhance
performance by modifying the capacity. In this paper the performance of a four storied reinforced
concrete building was
was
SAP2000 finite element analysis software package was used to obtain the capacity curve of the
building. The performance was evaluated using the capacity spectrum method proposed by ATC40
under the application of seismic demands derived from ATC40 document and AS1170.4 (2007)
standard.Results showed that the performance of the building is satisfactory in both X and Y
directions for all seismic demands determined using ATC40 document and ASH70.4 (2007).
