Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 1, March 2025.ABSTRACT Disaster insurance is gaining prominence as a tool to address climate‐induced loss and damage in developing countries. Despite ongoing efforts to pilot disaster insurance in Malawi, adoption by households remains low. This study examines factors influencing the adoption of disaster insurance in Malawi, a country highly susceptible to climate ...

A practical approach to meeting national obligations for sustainable trade under CITES
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract Reconciling conservation goals with sustainable resource use requires adaptive management strategies. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) regulates global trade for species listed on Appendix II, partly by requiring member countries (parties) to ensure exports do not damage wild ...

Gaoya dianqi, 2022 交流滤波器回路是特高压换流变电站的重要设备回路，但其特殊的结构特征导致其在强震作用下易发生破坏。为研究交流滤波器回路的地震易损性，文中通过有限元数值仿真计算的方法，对某800 kV换流站交流滤波器回路进行了数值建模，基于数值模型进行了模态分析和地震响应时程计算，并进行了回路地震易损性分析。结果表明：交流滤波器回路中的高压电容器和电阻器支柱绝缘子根部应力水平较高，有破坏风险；软母线的轴拉力远低于其计算拉断力；考虑母线耦联作用后，高压电容器和电阻器等应力较高的设备地震响应有所降低；PGA高于0.4g时 ...

Jianzhu Gangjiegou Jinzhan, 2022 鲁棒性是指结构对局部破坏的不敏感性。由于偶然荷载的不确定性，增强结构抗连续性倒塌的鲁棒性往往较直接抵抗偶然荷载更有效、更实用。但目前尚缺少公认的、通用的鲁棒性量化指标，阻碍了结构抗连续性倒塌分析与设计的发展。简要论述了连续性倒塌和不成比例倒塌的区别，以及鲁棒性与抗倒塌承载力、易损性、冗余度和韧性的区别。详细综述了基于结构属性、基于确定性结构性能、基于随机性结构性能的50余种结构鲁棒性定量判定方法，探讨了目前存在的关键问题和未来研究方向，主要集中在不同结构形式和倒塌模式的适用性、结构鲁棒性分级 ...

Gaoya dianqi, 2022 为了快速评估区域电网内所有变电站的主要设备在遭遇地震灾害时的震损风险，文中通过对历年来电力设备的震害调查资料进行统计分析，将区域地震动衰减规律与设备易损性分析过程结合，得到设备在地震作用下的震损概率与震级大小和震中距的关系。在此基础上提出了区域电网内变电站设备损毁情况的震前风险评估与震后快速评估方法，并通过算例进行了模拟评估。结果表明，设备的震损概率—震中距曲线可以表征设备地震易损性随空间分布的特征，是设备震损风险快速评估方法的核心内容；该方法可同时对区域电网内所有变电站进行震损风险评估 ...

Jianzhu Gangjiegou Jinzhan, 2019 通过对多层钢框架进行增量动力分析,研究柱脚转动刚度、底层破坏模式以及钢柱宽厚比对多层钢框架抗震性能的影响,具体从结构倒塌储备系数、地震易损性以及结构局部响应考察各影响因素对结构抗震性能的影响。分析结果表明,当破坏模式由钢柱破坏控制时,随着钢柱宽厚比的增大结构抗震性能减弱,考虑柱脚刚度的半刚接柱脚钢框架地震易损性与刚接柱脚钢框架差别较小,当柱脚与柱刚度比为2.0时,框架地震易损性与刚接柱脚钢框架非常接近;当破坏模式由柱脚破坏控制时,可以明显降低钢柱宽厚比的要求。
