飓风对美国墨西哥湾沿岸和东海岸构成了严重的金融威胁。这篇论文是一系列详细描述风和雨水入侵对轻型木结构建筑破坏的综合力学损失模型的配套论文中的第一篇。本文对经过的飓风的结构和危害模型进行了说明和论证。结构模型由非线性钉子模型集成到有限元模型中，并结合现有的风洞数据和雨水入侵模型建立了危险模型。提出了一种雨水入射量的计算方法。该方法与以前的方法不同，它允许通过将飓风通过期间划分为较小的时间增量来检查任何时间段，并允许载荷和阻力随时间段的变化而变化。因此，损坏和雨水入侵的时间和位置是已知的。配套的论文利用了v。
AbstractHurricanes present a serious financial threat to the Gulf Coast and eastern seaboard of the United States. This paper is the first in a set of companion papers that detail a comprehensive mechanistic loss model for wind and rainwater intrusion damage to light-frame wood buildings. In this paper the structural and hazard modeling for a passing hurricane is explained and demonstrated. The structural model consists of a nonlinear nail model integrated into a finite-element model, and a hazard model is developed using a combination of existing wind tunnel data and a rainwater intrusion model. A methodology to compute the rainwater entry volume is presented. The approach differs from previous methods in that it allows any time period to be examined by dividing the hurricane passage period into smaller increments of time and allows both load and resistance to change from time period to time period. Thus, the time and location of damage and rainwater intrusion is known. The companion paper utilizes the v...
