This project will perform integrated studies on earthquake ground motions. Stochastic modeling of earthquake ground motions will be performed and the results will be verified with field data. New techniques will be developed to process and analyze available ground motion data and provide input parameters for the verification. The stochastic modeling studies will provide the designer with a realistic and verified method for a seismic design. The seismic risk will be assessed using time histories of ground motion. As part of this work, new techniques to process strong motion data will be developed. The accuracy and numerical efficiency of existing processing algorithms will be evaluated based on site specific operating characteristics of ground motion instruments. A comparative evaluation of instrument performance will be made using a dense array of eight digital accelerographs.

该项目将对地震地面运动进行综合研究。 将进行地震地面运动的随机建模，并通过现场数据对结果进行验证。 将开发新技术来处理和分析可用的地面运动数据并为验证提供输入参数。 随机建模研究将为设计师提供一种现实且经过验证的地震设计方法。 地震风险将使用地面运动的时间历史来评估。 作为这项工作的一部分，将开发处理强运动数据的新技术。 现有处理算法的准确性和数值效率将根据地面运动仪器的特定特定操作特征进行评估。 仪器性能的比较评估将使用八个数字加速器的密集阵列进行。
