1995年的科比地震对科比市及其周边地区的建筑物和民用基础设施造成了前所未有的破坏。为了评估地震对该地区建筑物的破坏，估计地震地面运动的分布是非常重要的。然而，由于强震记录的数量是不够的，在严重受损的地区，它是必要的，估计分布使用其他数据源。本文利用AIJ和CPIJ小组密集实地调查的记录运动和建筑物损坏数据构建了低层住宅建筑的脆弱性曲线。然后利用得到的易损性曲线估计了地震期间科比及周边地区在区域水平上的强震分布。研究结果对探讨地震造成的各种破坏具有一定的参考价值。版权所有© 2001约翰威利父子有限公司
The 1995 Kobe earthquake caused unprecedented damage to buildings and civil infrastructures in the city of Kobe and its surrounding areas. In order to evaluate the structural damage in this area due to the earthquake, it is important to estimate the distribution of earthquake ground motion. However, since the number of strong ground motion records is not enough in the heavily damaged areas, it is necessary to estimate the distribution using other data sources. In this paper, the fragility curves for low‐rise residential buildings were constructed using the recorded motions and the building damage data from the intensive field survey by the AIJ and CPIJ group. The fragility curves obtained were then employed to estimate the strong motion distribution in the district level for Kobe and the surrounding areas during the earthquake. The results may be useful to investigate the various damages caused by the earthquake. Copyright © 2001 John Wiley & Sons, Ltd.
