摘　　要：本文从2012-2016年的150个合肥地区新建建筑物的评估样本中,选取具有地域、类型、功能代表性的高层A住宅单体和智能B办公楼作为评估对象,结合GB/T 21714.2-2008和GB/T 21714.2-2015新旧版本的计算方法对选取对象进行雷电灾害风险评估。结果表明,随着评估参数增删、定义、取值、公式的变化,新标准计算得到的人身伤亡损失风险R1一致减小,对后续的防雷设计、施工提供了可靠的数据参考。同时,对新旧标准的差异进行分析让雷电灾害风险评估工作的相关技术人员更好地学习与掌握新标准,为新标准的宣贯提供帮助。From the evaluation samples of 150 newly built buildings in Hefei from 2012 to 2016,this paper chooses highrise A residential units and intelligent B office buildings with geographical,type and functional representations as evaluation objects,and carries out lightning hazard risk assessment for selected objects by combining the calculation methods of GB/T 2174.2-2008 and GB/T 2174.2-2015.The results show that with the change of evaluation parameter,definition,value and formula,the risk of personal casualties calculated by GB/T 21714.2-2015 decreases unanimously,which has great influence on the subsequent lightning protection design and construction,and provides reliable data reference for it.At the same time,the differences between the old and new standards are interpreted,so that the relevant technical personnel of lightning disaster risk assessment can better learn and master the new standards,and provide help for the dissemination and consistency of the new standard.
