基于弹性和非弹性反应谱，研究了近断层脉冲型、近断层非脉冲型和远断层地震作用下结构反应的差异。作为第一步，检查的标准，以确定脉冲状的运动。地面运动方向的影响也进行了研究，考虑正常走向的方向，和运动的主要方向等。使用Veletsos-Newmark-Hall方法来合成光谱形状的特征，即，考虑弹性系统的响应放大系数和非弹性系统的响应折减系数。
The differences in structural response to near-fault pulse-like, near-fault non pulse-like, and far-fault ground motions are examined based on elastic and inelastic response spectra. As a first step, the criteria to identify pulse-like motions are examined. The influence of the ground motion orientation is also studied, considering the normal to strike orientation, and the principal directions of motion among others. The characteristics of the spectral shapes are synthesized constructing smoothed spectra using the Veletsos-Newmark-Hall methodology, i.e., considering response amplification factors for elastic systems and response reduction factors for inelastic systems.
