摘要本文提出了一种综合的、跨学科的方法，包括多物理、多尺度的数值模拟和模拟，从海啸的产生、传播和淹没到随后的耦合结构响应和相关的流体载荷。这种新颖、连贯的方法在大范围内执行这些模拟，使结构工程师能够充分利用海啸建模、地理空间数据收集和计算结构力学方面的最新进展中提供的细节。广泛的地震网络、大地测量仪器和水位站提供了前所未有的数据集，使人们能够高保真地模拟、模拟和重建海啸事件。一些协调一致的地面调查还收集有价值的、有时间敏感性的定量信息，以增进对海啸发生后的结构反应的了解。最近，其中一些调查包括高分辨率激光雷达测量，这提供了...
AbstractThis paper presents an integrated, interdisciplinary methodology incorporating multiphysics, multiscale numerical modeling and simulation from tsunami generation, propagation, and inundation to subsequent coupled structural response and associated fluid loads. This novel, cohesive approach performs these simulations across a large spectrum of scales, enabling structural engineers to take full advantage of the detail available in recent advances in tsunami modeling, geospatial data collection, and computational structural mechanics. Extensive seismic networks, geodetic instruments, and water-level stations provide unprecedented data sets, enabling one to model, simulate and reconstruct tsunami events with high fidelity. A number of coordinated, ground-based surveys also collect valuable, time-sensitive quantitative information to improve understanding of structural response to tsunami loading following events. Recently, some of these surveys include high-resolution LIDAR measurements, which provide...
