Interpretations of near-fault ground motions from 139 free-field stations of 1999 Chi-Chi earthquake show that, except for the hanging-wall and footwall effect generated by the dipping-fault geometry, directivity effect is also an important factor in considering the near-fault ground motions, which may largely affect the distribution and intensity of ground motion in near fault region. Based on the selected hard site ground motions, the peak ground acceleration, response spectra and time histories were investigated respectively. Results show that for similar site condition in the opposite directions of fault rupture (forward and backward), the characteristics of three components of ground motion, including fault-normal, fault-parallel and vertical, can varies significantly, mainly because of the constructive interference of radiated seismic energy, as the Chelungpu fault translated into predominantly left-lateral rupture in the north part.
