摘要
利用两个框架结构模型开展了一系列模拟试验,研究了框架结构建筑遭受雷击时雷电流的分布情况。研究结果表明:雷电流的分布情况随雷击点位置的变化而变化,距离雷击点越近,雷电流越大,距离雷击点越远,雷电流越小;当增加引下线的数量时,雷电流分布的畸变情况更加严重,距离雷击点较远的引下线上的雷电流明显减小,距离雷击点较近的引下线上的雷电流有一定程度的减小;单纯增加引下线数量不能明显改善雷电流的分布情况。根据研究结果,指出了框架结构建筑在雷电防护方面应注意的问题。
Based on two frame structure models,a series of simulation experiments are carried out to study the distribution of lighting current when a frame structure building is suffering from a lighting stroke.The result shows that:the distribution of the lighting current changes as the change of the location of the stroking point,and the nearer to the stroking point,the larger the lighting current is,which is the same on the contrary;when we add the number of down leads,the distortion of the lighting current is more serious than before,and the lighting current on the down lead which is far from the stroking point decreases much more than before and the lighting current on the down lead which is near to the stroking point decreases to some extent;only adding the number of the down leads can’t improve the distribution of the lighting current.According to the result,some suggestions are made on the lighting protection of frame structure buildings.
