ABSTRACT Tsunamis have received increased worldwide awareness since their unprecedented occurrences in the Indian Ocean and Tohoku in 2004 and 2011, respectively. In this study, the impact of tsunami on a building with an elevated floor slab was investigated at a reduced scale of 1:100 and compared with that of a slab-on-grade building. Three nominal wave conditions were tested to study the effects of tsunamis on each building model type. The tsunami-like wave forces and pressures on the building model were measured in the experiment. Results showed that the existence of an elevated floor slab significantly reduced the horizontal force on building upon the impingement of the initial wave. When the nominal wave height was higher than the building model height, the wave-induced horizontal force was overestimated by the Japanese design method. The maximum vertical resultant force on the elevated building model manifested a linear trend with increasing wave-exposed height up to a maximum force of approximately 3.8 N when the building model was fully submerged. This study also presented a proposed methodology for tsunami force estimation of the front and back faces of a building with an elevated floor slab.

马来西亚高架楼板海滨传统建筑的海啸力估算

摘要 海啸自 2004 年和 2011 年分别在印度洋和东北部发生前所未有的事件以来，已在全球范围内得到越来越多的关注。在这项研究中，海啸对高架楼板建筑物的影响以 1:100 的缩小比例进行了调查，并与楼板建筑的影响进行了比较。测试了三种名义波浪条件，以研究海啸对每种建筑模型类型的影响。在实验中测量了建筑模型上的类似海啸的波浪力和压力。结果表明，高架楼板的存在显着降低了初始波浪冲击时对建筑物的水平力。当名义波浪高度高于建筑模型高度时，日本设计方法高估了波浪引起的水平力。当建筑模型完全淹没时，高架建筑模型上的最大垂直合力呈线性趋势，随着波浪暴露高度的增加，最大力约为 3.8 N。本研究还提出了一种建议的方法，用于估计具有高架楼板的建筑物的正面和背面的海啸力。
