Abstract

The article presents a probabilistic criteria for the damage and loss assessment of buildings exposed to strong wind hazard. The criteria include the development of fragility curves, within the Federal Emergency Management Agency style, for appropriate damage states on a hotel building and contents due to the loss of nonstructural elements, like facades and the partial or total loss of contents because of water infiltration. The loss estimation includes loss components like the business interruption due to repairs/reconstruction work and, throughout a new estimation that considers mitigation measures to upgrade the building, it is shown that these measures reduce the loss in a significant level. The probabilistic description of wind-induced pressure on facades and windows resorts on the wind velocity distribution, and their resistances consider data and statistics from manufacturers. The calculation of failure probabilities makes use of Monte Carlo simulations for the considered modes: windows/façade anchorage failure, glass braking due to wind pressure and impact of airborne debris. The probabilistic distribution of rainfall, given the occurrence of a hurricane and the subsequent water infiltration, serves to assess damages on structures under strong wind hazard. A hotel building recently damaged by the hurricane Odile in Baja California Sur, México is used to illustrate the formulation. The results may help to promote funds allocation for hurricanes and to propose improvements to the current wind design code in México.

墨西哥强风下建筑物损坏和损失的概率评估

摘要

本文提出了一种用于评估遭受强风灾害的建筑物的损坏和损失的概率标准。该标准包括按照联邦紧急事务管理署的风格制定脆弱性曲线,用于显示由于外墙等非结构元素的损失以及由于水渗入导致的部分或全部内容物损失而导致的酒店建筑和内容物的适当损坏状态。损失估计包括损失部分,例如由于维修/重建工作造成的业务中断,并且在考虑升级建筑物的缓解措施的新估计中,表明这些措施可以显着减少损失。外墙和窗户上的风致压力对风速分布的概率描述,他们的阻力考虑了制造商的数据和统计数据。失效概率的计算利用蒙特卡罗模拟所考虑的模式:窗户/外墙锚固失效、风压引起的玻璃制动和空中碎片的影响。考虑到飓风的发生和随后的水渗入,降雨的概率分布有助于评估强风灾害下结构的损坏情况。最近在墨西哥南下加利福尼亚州被飓风奥迪尔损坏的酒店大楼被用来说明这个公式。结果可能有助于促进飓风的资金分配,并建议改进墨西哥当前的风能设计规范。失效概率的计算利用蒙特卡罗模拟所考虑的模式:窗户/外墙锚固失效、风压引起的玻璃制动和空中碎片的影响。考虑到飓风的发生和随后的水渗入,降雨的概率分布有助于评估强风灾害下结构的损坏情况。最近在墨西哥南下加利福尼亚州被飓风奥迪尔损坏的酒店大楼被用来说明这个公式。结果可能有助于促进飓风的资金分配,并建议改进墨西哥当前的风能设计规范。失效概率的计算利用蒙特卡罗模拟所考虑的模式:窗户/外墙锚固失效、风压引起的玻璃制动和空中碎片的影响。考虑到飓风的发生和随后的水渗入,降雨的概率分布有助于评估强风灾害下结构的损坏情况。最近在墨西哥南下加利福尼亚州被飓风奥迪尔损坏的酒店大楼被用来说明这个公式。结果可能有助于促进飓风的资金分配,并建议改进墨西哥当前的风能设计规范。考虑到飓风的发生和随后的水渗入,用于评估强风危害下结构的损坏情况。最近在墨西哥南下加利福尼亚州被飓风奥迪尔损坏的酒店大楼被用来说明这个公式。结果可能有助于促进飓风的资金分配,并建议改进墨西哥当前的风能设计规范。考虑到飓风的发生和随后的水渗入,用于评估强风危害下结构的损坏情况。最近在墨西哥南下加利福尼亚州被飓风奥迪尔损坏的酒店大楼被用来说明这个公式。结果可能有助于促进飓风的资金分配,并建议改进墨西哥当前的风能设计规范。
