THE EFFECT OF A PREDOMINANT PULSE PERIOD (Tp) HANGING WALL, AND FOOTWALL IN THE NEAR-FAULT GROUND MOTIONS ON A SINGLE DEGREE OF FREEDOM SYSTEM (SDOF)

Abstract

This paper aims to study the responsiveness of buildings with a single degree of freedom system in near-fault under the influence of the hanging wall and the footwall in addition to studying the influence of the predominate pulse in this type of ground motion, where it turns out when taking the readings that most of the mechanical motion of the ground in the area of the near-fault is of the reverse type and this is what calls to study the impact of the hanging wall and the footwall. Strong ground motion data were taken for different events in different places around the world and the ground motion parameters were used which are the peak acceleration of the Earth (PGA), peak velocity of the Earth (PGV), peak displacement of the earth (PGD), prevailing frequency content (TP).
