摘　　要：对建筑物的雷击年损坏风险R值进行分析。基于理论建立R值的计算模型,将建筑物的防雷等级提高一个档次后,对R值降低的程度进行分析。对比计算结果可知,提高防雷等级后,R值最大下降百分比约50%。对比结果可对建筑物的防雷等级提供参考。This paper studies the analysis of the annual damage risk R value of buildings caused by lightning.Based on the theory,the calculation model of R value is established to improve the lightning protection level of buildings by one grade,and the specific degree of R value reduction is analyzed.According to the calculation results and comparison,the maximum reduction percentage of R value is 50%by increased the lightning protection level.It has certain reference value for the lightning protection level of buildings.

关 键 词：年损坏风险R值 防雷装置 年预计雷击次数 防雷等级
