摘要: The hanging wall effect is an important factor that impacts the characteristics of strong ground motions in near-fault areas. Based on a residual analysis motion parameters characterizing and recognition nature effect, many models have been developed. In this study, after comprehensive two existing models, new model proposed used to horizontal peak acceleration (PGAH) spectral (SAH) at period 0.1 s Wenchuan earthquake. Finally, comparisons between modeling results earthquake predicted by using Abrahamson Silva’s NGA (AS NGA) indicate AS predicts much higher than developed paper. Furthermore, large even great distances, while more accurately captures trend effect.
