摘要
为了计算雷击建筑物时雷电流在建筑物的金属构架中的分布及内部空间电磁场的分布情况，分析现代建筑的防雷保护系统对建筑物内电子系统的雷电防护效果，依据现代建筑物所采用的“法拉第笼”式暗装避雷网，利用Visual Basic 6．0设计、编写了相应的防雷计算软件。利用这一软件可计算建筑物遭受雷击时金属构架中的电流分布和室内磁场的分布情况。并可直观地显示防雷系统的防护效果，为实际工程的设计、施工和检测提供有力的依据。
In order to calculate the surge current distribution in a reinforced concrete structure and electromagnetism distribution within the buildings when buildings were struck by lightning, and to analyze the protective effect of lightning protection system of the electronic systems in the modern building, mainly based on the Faraday＇ s cover lightning protection of modern building, using Visual Basic 6.0, the appropriate calculating software was designed and programmed. It can be used to calculate the distribution of lightning current in the building＇ s metal structure and lightning electromagnetism in the buildings when lightning struck buildings. The protective effect of lightning protection system was shown directly. It can provide strong support for design, construction and examination for the actual projects.
