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.

对特定国家或区域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，建筑物改造和重建方案的成本效益分析需要确定建筑物复原力的增加情况。这涉及对翻新/重建前后的脆弱性进行量化。关于受热带气旋（TC）灾害影响的低工程建设，最近的破坏性事件和随后的损害评估增加了经验为基础的脆弱性功能的可用性。然而，这些仅限于特定的地点和事件，与特征明确的结构类型及其响应关系不大。此外，从实地获得的关于具体改装解决办法的执行程度和绩效的证据非常有限，包括其成本。因此，有必要应对上述挑战，以确定经改进和验证的脆弱性函数，并量化改造/重建前后脆弱性的变化。
