摘要风致雨（WDR）通过建筑围护结构缺陷和破坏侵入是飓风登陆期间建筑内部构件和内容物损坏的主要来源。建筑物内部总损坏程度（对建筑物内部构件、公用设施和内容物的损坏）是WDR侵入总量的函数，而WDR侵入总量又取决于开口尺寸、风速和雨强。目前，通过建筑物立面上的给定开口的雨水入侵量估计使用半经验模型，使用基于工程判断的参数信息。本文提出了一种基于测试的WDR入侵模型，它使用的参数值，通过测试模拟WDR条件下的建筑模型。该模型估计雨水入侵的总体积，通过一个开放的总和的WDR体积归因于直接撞击雨滴和地表径流雨水从未受损的信封区。基于测试的WDR ...
AbstractWind-driven rain (WDR) intrusion through building envelope defects and breaches is a major source of damage to building interior components and contents during hurricane landfall. The extent of total building interior damage (damage to building interior components, utility, and contents) is a function of the total volume of WDR intrusion which in turn is dependent on the size of openings, wind speed, and rain intensity. Currently, the volume of rainwater intrusion through a given opening on a building facade is estimated using a semiempirical model with use of parametric information based on engineering judgment. This paper presents a test-based WDR intrusion model which uses values of parameters developed through testing of building models under simulated WDR conditions. The model estimates the total volume of rainwater intrusion through an opening as a summation of WDR volume attributable to direct impinging raindrops and surface runoff rainwater from the undamaged envelope area. Test-based WDR ...
