Abstract We examined a potential strategy for mitigating injury and death during tsunamis by conducting numerical simulations for a vertical-evacuation structure with a breakaway ground floor. The simulation produced the uplifting load on the bottom slab, the frontal impact force and the overturning moment, depending on the structure's size and bottom-slab elevation, and the wave's Froude number. With a proper normalization, the force and moment coefficients were generalized to become not explicitly dependent on the height of the bottom slab. The exposure of the bottom slab to wave impact has increased the probability of the structure to overturn. Based on our findings, we propose a maximum moment coefficient of 0.84 to decide on the overturning stability of the structure.

海啸波浪力对高架海岸结构的影响

摘要 我们通过对具有分离底层的垂直疏散结构进行数值模拟，研究了在海啸期间减轻伤害和死亡的潜在策略。模拟产生了底板上的抬升载荷、正面冲击力和倾覆力矩，具体取决于结构尺寸和底板高程以及波浪的弗劳德数。通过适当的归一化，力和力矩系数被概括为不明确依赖于底板的高度。底板暴露于波浪冲击增加了结构倾覆的可能性。根据我们的研究结果，我们提出了一个最大弯矩系数 0.84 来决定结构的倾覆稳定性。
