Abstract Performance-based wind engineering (PBWE) is undergoing a period of rapid development with numerous procedures and frameworks being proposed over the past few years. Notwithstanding these advancements, there is still a knowledge gap concerning the relative severity, dependency and rate of occurrence of structural and envelope damage in extreme wind events. This work is focused on investigating this problem for engineered buildings. In particular, envelope damage is estimated through a recently introduced PBWE framework that explicitly includes the effects of demands originating from dynamic net pressure and the structural responses. Structural damage is estimated through both fragility analysis as well as material yielding/hysteresis modeled through the adoption of a nonlinear fiber-based finite element formulation. Structural responses include the effects of large deformations through solving the finite element model in a corotational environment. To investigate the relative severity and dependency between the damages, a carefully calibrated archetype 45-story steel building located in Miami, FL, and subject to hurricane winds is studied. Probabilistic damage metrics are estimated for both the envelope and structural systems and are subsequently discussed in terms of relative severity, occurrence rates and nonlinear structural behavior.

通过非线性动力分析对工程建筑进行基于性能的风致结构和围护结构损伤评估

摘要 基于性能的风工程（PBWE）正在经历一个快速发展的时期，在过去几年中提出了许多程序和框架。尽管取得了这些进步，但在极端风事件中结构和外壳损坏的相对严重性、依赖性和发生率方面仍然存在知识差距。这项工作的重点是研究工程建筑的这个问题。特别是，通过最近引入的 PBWE 框架估计包络损坏，该框架明确包括源自动态净压力和结构响应的需求的影响。结构损坏通过脆性分析以及通过采用基于非线性纤维的有限元公式建模的材料屈服/滞后来估计。结构响应包括通过在共转环境中求解有限元模型而产生的大变形的影响。为了调查损害之间的相对严重性和相关性，研究了位于佛罗里达州迈阿密并受到飓风风影响的精心校准的原型 45 层钢结构建筑。估计围护结构和结构系统的概率损坏指标，然后根据相对严重程度、发生率和非线性结构行为进行讨论。
