NSF Young Investigator

该行动旨在为概率力学和地震工程的研究提供支持，重点是：1)利用随机有限元方法分析具有随机特性的结构；2)利用三维地震波解析推导地震地震动谱；3)随机过程、场和波的模拟；4)疲劳敏感结构的贝叶斯分析非周期性检测。本奖项符合NSF 91-112“青年研究者奖1992年度项目提名提交指南”中的条件。本研究结果可应用于结构系统分析的工程设计过程，包括对地震产生的地面运动的反应。

This action is to provide support for research in probabilistic mechanics and earthquake engineering, with emphasis on: 1) analysis of structures with random properties using stochastic finite element methods, 2) analytic derivation of seismic ground motion spectra using three-dimensional seismic waves, 3) simulation of stochastic processes, fields and waves, and 4) non-periodic inspections of fatigue-sensitive structures by Bayesian analysis. This award is in accord with conditions contained in NSF 91-112, "Young Investigator Awards FY 1992 Program Guidelines for Submission of Nominations". Results of this research may be applied to engineering design processes for the analysis of structural systems, including the response to earthquake-generated ground motions.
