摘要分析了雷击高层建筑物时,电流分布特征。雷电流分布的计算,必须先确定各个分支导体的电气参数,本文采用平均电位法计算钢筋分支导体的电容参数,电感参数用牛依曼公式计算,对于各钢筋分支间存在的电磁耦合,分别以参数的矩阵形式描述。根据以上算法,利用Matlab编制计算机程序,求得各个支路的电容和电感参数.再利用ATPDRAW软件进行仿真。计算的结果与仿真的结果能较好的符合。

Abstract：The lightning current distribution characteristics of tall buildings struck by lightning was analyzed. The electrical parameters of every conductor were calculated first so as to calculate the current distribution in a tall building. The capacitance matrix of conductor branches is determined in terms of the average potential method, and the inductance matrix of conductor branches is calculated by Neuman’s formula. The electromagnetic coupling within every reinforcing steel conductor is described as parameter matrix form. According to the above algorithm, using the Matlab computer program, we can obtain the capacitance and inductance parameters of each branch, after that use ATPDRAW software for simulation. The calculation results were well consistent with the simulation results.
