Lightning strike probability and current simulation for simple structures and floating roof tank
Alexandria Engineering Journal, 2022 Air terminations must be strategically positioned at high-risk points to prevent lightning bypass. The likelihood of a direct lightning strike to points on a building can be evaluated using the dynamic electro-geometrical model (DEGM), which considers ...
