摘要
分析了雷电灾害风险评估中"截收面积"计算公式的单一性和局限性,将目前常见的形状复杂的建筑物划分为三大类(即"有一制高点的矩形建筑物、裙楼建筑物和L形建筑物")并形成模型。依据《建筑物电子信息系统防雷技术规范》GB50343—2012,通过"Auto CAD"画图软件画出相应模型的截收面积图,归纳得到对应模型截收面积的计算公式。经过实例对比,发现较经验法获取的形状复杂建筑物的截收面积更为精确,为雷电灾害风险评估中截收面积的快捷计算提供科学参考。
An analysis is made of the uniqueness and limitation of the collection area calculation formula in the evaluation of lightning disaster risk. The common complex-shaped structures are divided into three categories： rectangular building with a high point, podium building, and L-shaped building, and the corresponding models are formed. According to the Technical Codes for Protection of Building Electronic Information System against Lighting （GB50343-2012） by using the Auto CAD software. The corresponding empirical method, the results o references for the evaluation of e calculation method lightning disaster risk an appropriate model of collection area is devised model formula is generalized. Comparing to the is close to true values, which provides scientific
