The role of input energy in assessing seismic hazard and damage following the Turkey earthquakes

CMS-0085301手册1999年土耳其地震后输入能量在评估地震灾害和损失中的作用本研究的主要重点是检查基于能量的地面运动描述符与土耳其最近1999年地震期间观测到的损害空间分布的相关性程度。其次是比较传统的基于强度的描述符(如频谱加速度)和这些基于能量的描述符。概率地震危险性分析将使用这两个与频率相关的地面运动参数。经修订的衰减模型包括最近地震的数据(重点是记录的近断层运动)，这将增强当前的数据库，减少危险估计的不确定性。只要有土壤剖面信息，就会尝试将场地效应纳入灾害评估。短期工业建筑、住宅和办公楼的损伤数据将从不同地区收集，并将与输入能量和频谱加速度需求进行空间关联。这项研究的成果将包括新的预测衰减模型，以及对基于能量的地面运动描述符的重要性以及场地效应对地震危险性和对短期和长期结构破坏的作用的理解。

CMS-0085301ManuelThe Role of Input Energy in Assessing Seismic Hazard and Damage following the 1999 Turkey EarthquakesThe main focus of this study is to examine the extent of correlation of energy-based descriptors of ground motion with the observed spatial distribution of damage during the recent 1999 earthquakes in Turkey. Of secondary interest is a comparison between more conventional strength-based descriptors (such as spectral acceleration) and these energy-based descriptors.Probabilistic seismic hazard analyses will be performed using both of these frequency-dependent ground motion parameters. Revised attenuation models including data from the recent earthquakes (with emphasis on recorded near-fault motions) will enhance the current database and reduce uncertainty in hazard estimates. Whenever soil profile information is available, attempts will be made to include site effects in the hazard estimates.Damage data for short-period industrial structures and for residential and office buildings will be collected from various regions and will also be correlated spatially with input energy and spectral acceleration demands.Products of this study will include new predictive attenuation models as well as an understanding of the importance of energy-based ground motion descriptors and of the role of site effects on seismic hazard and on damage to short- and long-period structures.
