Abstract
In this paper characteristics of near-field earthquakes and difference of ground motion response key parameters in these earthquakes, based on real records of Iran are presented and efficiency of Iranian seismic building code for design of buildings subjected to near-field earthquakes is evaluated. The equivalent static method to calculate the lateral earthquake force exerted on buildings, is common and extensively used. Iranian code of practice for seismic resistant design of buildings, Standard No.2800-05, uses V= (ABI /R)*W relationship to calculate this lateral force. Where A (=design basis acceleration over the bedrock) and B (=the amplification factor) are related to earthquake, and near-field earthquakes may induce dramatically high response in fixed-base building. In this research peak ground acceleration over the bedrock & amplification factor suggested by Iranian Standard No.2800-05 are assessed according to near field earthquake records in Iran and also the results are compared with UBC97 code. The outcomes show the inefficiency of Standard No.2800- 05 for calculating the near source structures. Furthermore, according to this study, a design spectrum is suggested for Iran which it can be used in both near field and far field regions.
