چکیده:
In this article responses of seven story building excited by the horizontal component of fault-parallel (permanent) displacement and fault-normal pulses with different magnitudes and time lags are investigated. In the considered model each storey consist of a rigid beam connected to two axially rigid mass-less columns by linear rotational springs and dashpots. The system of coupled equations of motion has been solved by the fourth-order Runge-Kutta method .The drift responses show that time lag of input ground motion records has influence on structure responses. Because of the large initial velocity present in the ground motion near earthquake faults the story drifts quickly exceed the typical design levels and fault-normal pulses produce more intense drift demands relative to those for fault-parallel displacements and it must be noticed in near fault zone designs.
