Gerenciamento de risco para determinação da necessidade de sistemas de proteção contra descargas atmosféricas em edificações: um estudo de caso

Abstract

Atmospheric discharges are unpredictable natural phenomena that can cause various impacts, ranging from minor structural damage to the death of animals and humans. Considering the high occurrence of these phenomena in Brazil, it is important that large buildings, especially those where a significant number of people reside and/or circulate, undergo a technical analysis to determine whether protective measures are necessary, such as the installation of a Lightning Protection System (LPS), which aims to mitigate damage caused by lightning strikes directly to the building or its surroundings. This study presents the main theoretical concepts related to atmospheric discharges, general aspects concerning LPS, and the methodology for risk analysis of structural losses. Finally, a case study is presented, which involves risk management conducted to assess the need for installing an LPS or other protective measures in a building located in the city of Sobral-CE.
