Abstract:

This paper investigates the correlation between near –field seismic parameters and damage index in concrete buildings and then compares obtained results with those observed in related to far – field seismic parameters. The excitations such as PGA, PGV, PGD, Arias Intensity and SED are extracted from near and far field seismic records for characterizing the seismic excitation. On the other side, structural damage index is expressed by the modified Park /Ang overall structural damage index (OSDI). After the evaluation of seismic parameters, Nonlinear Dynamic Analysis on the three concrete frames reinforced by shearwall and three moment resisting frames (MRF) are carried out to observe response parameters. The degree of the interrelationship between mentioned seismic parameters and strucural damages are determined by correlation coefficients. Finally as a result with observing these coefficients, those parameters play significant role to predict structural damages, are known. In related to near – field records, Results indicate there is high correlation between PGV and SED and damage index. Also it is revealed that degree of correlation is increased with increasement of height and period of structure. Findings show that about tall concrete buildings which are subjected near – field ground motions, PGV and SED especially PGV can be used as parameters to predict structural damages.

Keywords:

Near- Field Ground Motion, Damage Index, Seismic parameters, shearwall
