Effect of Vertical Component of Near-Field Earthquake on the Structural

Abstract. Records of near field earth quack have special specification because of nearness of wavepropagation that it makes difference their behavior than other records. Near field earth quick havehigher acceleration and more limited frequency in high frequency than far field. Record of theseearth quick, especially when they are under fault propagation, has long period pulses with big areathat they often seen in the first of record. In this study, the effect of vertical element of near fieldearth quick on three steel buildings 4,8,12...
