NEESR-SG: Development of Performance Based Tsunami Engineering, PBTE

摘要海啸对世界各地的沿海社区和基础设施构成重大威胁。在许多情况下，由于潜在的当地海啸源头或需要疏散的人数，水平疏散是不可能的。对现有建筑或新的急救中心进行评估或设计以进行垂直疏散是至关重要的。然而，关于海啸对建筑物、桥梁和港口设施等沿海基础设施的影响的研究一直很缺乏。此外，还缺乏设计指南。为了克服这一不足，这项研究将开发实施基于现场具体性能的海啸工程(PbTe)的方法和工具，用于沿海结构和设施的分析、评估、设计和翻新。这项工作的技术重点是流-结构相互作用的模拟，结构荷载时程的发展，以及在非线性结构分析中的应用，以确定所建设施的预期性能。重要的潜在成果包括：PbTe方法；改进和验证的分析工具；抗海啸结构设计的要求，包括与建筑规范兼容的准则；业绩水平规格；在外联和教育方面的重大努力；以及结果的传播。

ABSTRACT Tsunamis pose a significant threat to coastal communities and infrastructure throughout the world. In many cases horizontal evacuation is not possible due to the potential local source of the tsunami or the number of people to be evacuated. It is essential that existing buildings, or new emergency centers, be evaluated or designed for vertical evacuation. However, there has been a lack of research on the effect of tsunami waves on coastal infrastructure such as buildings, bridges, and harbor facilities. Furthermore, design guidelines are lacking. To overcome this deficiency, this research will develop the methodology and tools for implementation of site specific Performance Based Tsunami Engineering (PBTE) for use in the analysis, evaluation, design and retrofit of coastal structures and facilities. The technical focus of the work is the simulation of fluid-structure interaction, development of structural loading time histories, and the application of these in a non-linear structural analysis to determine the expected performance of the constructed facilities. Significant potential outcomes include: PBTE methodology; refined and validated analysis tools; requirements for tsunami-resistant structural design, including building code compatible guidelines; performance level specifications; significant efforts in outreach and education; and dissemination of the results.
