The influence of a building array on tsunami-driven run-up loads is studied through laboratory experiments and Computational Fluid Dynamics (CFD) simulations. Results show that the number of rows of buildings providing shelter is an explanatory variable for the maximum wave run-up load reduction. Load Reduction Factors (LRF) are defined, with values monotonically decreasing as the number of rows providing shelter increases. The effect of the building array on maximum inundation levels, maximum cross-shore velocity, and maximum momentum flux is studied, finding that these hydrodynamics properties have larger magnitudes when compared to bare earth values. A brief discussion about the effect of the cross-shore distance between rows, the width of the structures in the frontmost row, and the offset between rows is presented. Under the wave conditions and the geometry tested, maximum wave loading is decreased up to about 4 times when 4 or more rows are providing shelter, with most of the load reduction taking place in the first 4 rows. When more than 4 rows are providing shelter to a structure of interest, Load Reduction Factors decrease weakly with the number of rows providing shelter. Although the present analysis has limitations in terms of geometry and wave conditions and more tests have to be conducted to draw conclusions for a wider range of conditions, it shows experimental and numerical evidence that maximum wave loading on structures can be strongly affected when they are part of a building array.

通过实验室实验和计算流体动力学 (CFD) 模拟，研究了建筑物阵列对海啸驱动的启动载荷的影响。结果表明，提供庇护所的建筑物的行数是最大波浪爬升载荷减少的解释变量。定义了负载减少因子 (LRF)，其值随着提供庇护所的行数的增加而单调递减。研究了建筑物阵列对最大淹没水平、最大跨岸速度和最大动量通量的影响，发现与裸地值相比，这些流体动力学特性具有更大的量级。简要讨论了行间跨岸距离、最前行结构宽度和行间偏移的影响。在波浪条件和测试的几何形状下，当 4 行或更多行提供庇护时，最大波浪载荷减少了大约 4 倍，其中大部分负载减少发生在前 4 行。当超过 4 行为感兴趣的结构提供遮蔽时，减载系数随着提供遮蔽的行数而微弱地减少。尽管目前的分析在几何形状和波浪条件方面存在局限性，并且必须进行更多的测试才能在更广泛的条件下得出结论，但它显示了实验和数值证据，表明结构上的最大波浪载荷可能会受到强烈影响。的建筑阵列。大部分负载减少发生在前 4 行。当超过 4 行为感兴趣的结构提供遮蔽时，减载系数随着提供遮蔽的行数而微弱地减少。尽管目前的分析在几何形状和波浪条件方面存在局限性，并且必须进行更多的测试才能在更广泛的条件下得出结论，但它显示了实验和数值证据，表明结构上的最大波浪载荷可能会受到强烈影响。的建筑阵列。大部分负载减少发生在前 4 行。当超过 4 行为感兴趣的结构提供遮蔽时，减载系数随着提供遮蔽的行数而微弱地减少。尽管目前的分析在几何形状和波浪条件方面存在局限性，并且必须进行更多的测试才能在更广泛的条件下得出结论，但它显示了实验和数值证据，表明结构上的最大波浪载荷可能会受到强烈影响。的建筑阵列。
