2016年8月24日,一个强震(M6.0~6.2)袭击了位于意大利地震最活跃地区之一的亚平宁山脉中部。现场调查表明,震中区破坏严重,并造成人员伤亡,大范围文化遗产和重要建筑物遭受破坏。利用新的确定性地震危险性评估法(neo-deterministic seismic hazard assessment,NDSHA),我们将最大确定性地震输入(maximum deterministic seismic input,MDSI)方法应用于震中区最相关的两个场地,并将结果与当前意大利建筑规范进行了比较。在完成快速工程分析后,我们结合表征地震输入的震源和场地效应,解释了造成报道的建筑环境的高地震易损性破坏的可能原因。因此,利用合适的谱加速度水平结合未来可能发生的地震事件,例如由MDSI提供的可能事件,进行建筑物设计和翻新至关重要。
On August 24, 2016, a strong earthquake (M6.0-6.2) hit the middle of the Apennines, one of the most active areas in the Italian earthquake. Field investigations showed that the epicenter area was severely damaged and resulted in casualties and the destruction of a wide range of cultural heritage and important buildings. Using the new deterministic seismic hazard assessment (NDSHA), we apply the maximum deterministic seismic input (MDSI) method to the two most relevant sites in the epicenter area, The result is compared with the current Italian building code. After completing the fast engineering analysis, we combine the hypocenter and site effects characterizing the seismic inputs to explain the possible causes for the high earthquake vulnerability of the built environment. Therefore, it is crucial to design and retrofit a building with the appropriate level of spectral acceleration in conjunction with future seismic events that may occur, such as the possible events provided by the MDSI.
