高层民用建筑雷击风险评估设计思想及实例分析

通过分析高层民用建筑的建筑特性、位置特点和气象条件,阐述了高层民用建筑进行雷击风险评估的必要性。对高层民用建筑进行雷击风险评估的内容、程序和方法进行研究,探讨了影响高层民用建筑风险的各种因子、风险分量,通过系列的计算方法得到人身伤亡风险值。通过对风险分量和总风险值分析对比分析,得出雷电灾害主要的影响因子和风险分量,针对性地提出安全可靠、经济合理的雷电防护措施。

Design and Analysis of Lightning Risk Assessment in High-rise Civil Buildings

Through the analysis of location charaeteristics, meteorological conditions, and constntction charactcristics of high-rise buildings, the necessity and significance of lightning risk assessment were determined in high-risecivil buildings. The contents, procedures and methods of lightning risk assessment werc researched, and the influencing factors and components on the risk of personal injury were analyzed. The risk value was obtained hv calculation. By contrast study on risk component and total risk, the main influencing factors of lightning disaster and risk component were obtained. The safe, economic and reasonable lightning protection measures were proposed at last.
