Vulnerability functions for Tropical Cyclones Triggered Disaster Risk and Resilience

对特定国家或地区的风险分析需要适合当地情况的脆弱性函数，以便准确地表示风险。此外，建筑翻新和重建方案的成本效益分析需要确定建筑复原力的增加。这涉及量化改造/重建前/后的脆弱性。对于受热带气旋(TC)危害影响的低工程建筑，最近的破坏性事件和随后的损害评估增加了基于经验的脆弱性函数的可用性。然而，这些仅限于特定的地点和事件，与具有良好特征的结构类型及其反应的关联性很差。此外，关于具体改装解决方案的实施程度和绩效，包括其费用，从实地获得的证据非常有限。因此，有必要解决上述挑战，以确定改进和验证的脆弱性功能，并量化改造/重建前后脆弱性的变化。

Risk analyses for specific nations or regions require locally-appropriate vulnerability functions in order to accurately represent risk. In addition, cost-benefit analyses for building retrofitting and reconstruction programmes requires determining the increase in building resilience. This involves quantifying the vulnerability pre/post retrofit/reconstruction. In relation to low engineered construction affected by Tropical Cyclone (TC) hazards, recent destructive events and subsequent damage assessments have increased the availability of empirically based vulnerability functions. However, these are limited to specific locations and events and poorly associated to well characterised structural typologies and their response. Moreover, there is very modest evidence from the field of the extent of implementation and performance of specific retrofitting solutions, including their cost. Hence, it is necessary to tackle the above challenges in order to define improved and validated vulnerability functions, and quantify the changes in vulnerability pre/post retrofit/reconstruction.
