Abstract In this paper, the calculation method of shielding effect of lightning electromagnetic field is given. Through the calculations of the shielding effect of lightning electromagnetic field of the 32 tall buildings built in Baoding in recent years, it is found that the top floor of tall buildings basically can not be used as the electronic computer room, and only a few parts of the second top floor can meet the requirements in the codes. It is proposed that in the design of tall buildings，the architectural design sectors do the necessary calculations to ensure the rationality of location design of the electronic computer room.

摘 要 给出了计算雷电电磁场屏蔽效果的计算方法，通过对保定市近年来所建32栋高层建筑雷击电磁场屏蔽效果的计算，发现高层建筑的顶层基本不能做电子机房使用，顶二层只有个别部位能满足规范要求。建议建筑设计部门在高层建筑设计中做必要的计算，以保证电子机房位置设计的合理性。
