摘要
基于年预计雷击次数在建筑物防雷保护中的研究现状,对比分析了GB 50057—1994和GB 50057—2010的异同.针对当前常用计算工具缺陷,依据GB 50057—2010预计雷击次数计算方法,使用Delphi 7.0编写了一种建筑物年预计雷击次数计算软件.该计算软件能够根据建筑物特点快速地计算出建筑物预计雷击次数,显示出校正系数和雷击等效面积数值.
According to current research status of annual estimated numbers of lightning strikes in buildings lightning protection,the similarities and differences between GB 50057—94 and 2010 edition are analyzed with comparative method.Based on the GB 50057—2010 calculation method,a software for calculate annual expected numbers of buildings lightning strikes is designed in Delphi 7.0.According to the building characteristics,the estimated number of times,correction coefficient and lightning equivalent area value can be calculated quickly in this software.
