“…It is well known that this discharged energy heats up a considerable amount of air surrounding the core of the lightning. The temperature rise is so rapid and significant that it can start fires near the location where lightning strikes [37]. Furthermore, when lightning strikes a building, the electric current passes through the structure, which leads to a sudden heat generation and a rapid increase of temperature [29,37,38].…”

This study investigated the failure of the roof, with steel truss construction, of a factory building in Tekirdag in the northwestern part of Turkey. The failure occurred under hefty weather conditions including lightning strikes, heavy rain, and fierce winds. In order to interpret the reason for the failure, the effects of different combinations of factors on the design and dimensioning of the roof were studied. Finite element analysis, using the commercial software Abaqus (Dassault Systèmes, Vélizy-Villacoublay, France), was performed several times under different assumptions and considering different factors with the aim of determining the dominant factors that were responsible for the failure. Each loading condition gives out a characteristic form of failure. The scenario with the most similar form of failure to the real collapse is considered as the most likely scenario of failure. In addition, the factors included in this scenario are expected to be the responsible factors for the partial collapse of the steel truss structure.

“…Previous research proved the heating effects of the lightning strike phenomenon [35,36]. It is known that a lightning strike increases the temperature rapidly in a very short period of time [29,37]. The electric current that is caused by the lighting strike heats up the structure so that it can start fires [38].…”

“…The temperature rise is so rapid and significant that it can start fires in near the location where lightning strikes [37]. Furthermore, when lightning strikes a building the electric current passes through the structure which leads to a sudden heat generation and a rapid increase of temperature [29,37,38]. Besides, quite large shock forces occur due to the interaction of a large mass of hot and cold air around it, and also due to the humidity of the air and the ground, which is called the blast effect.…”

This study investigates the failure of a roof with steel truss construction of a factory building in Tekirdag in North-western part of Turkey. The failure occurred under hefty weather conditions including thunderbolt, lightning strikes, heavy rain and fierce winds. In order to interpret the reason for the failure, the effects of different combinations of factors on the design and dimensioning of the roof are checked. Therefore, finite element analysis is performed several times under different assumptions and considering different factors aiming to determine the dominant ones that are responsible for the failure using the commercial software Abaqus (Dassault Systèmes, Vélizy-Villacoublay, France). Each loading condition gives out a characteristic form of failure. The scenario with the most similar form of failure to the real collapse is considered as the most likely scenario of failure. Also, the factors included in this scenario are expected to be the responsible factors for the partial collapse of the steel truss structure.

“…The national risk of lightning resulting in death to people is usually derived from the average number of lightning fatalities in relation to the total population (Holle, , ; Elsom, ). For example, in the UK for the 9‐year period of this study (2008–2016), there were nine known fatalities recorded by TORRO and listed by government statistical agencies as deaths in which lightning was the underlying cause of death (Elsom and Webb, , , , ). The average population during this period was 63.7 million, so the risk of lightning causing a fatality was 1/63.7 or 0.016 per million population per year (M −1 yr −1 ), or simply one death per 64 million people.…”

New estimates of lightning counts from the Met Office ATDnet system are obtained for the ‘UK land area’ and compared with those currently available for the ‘UK service area’ (which includes Republic of Ireland and surrounding seas). Annual counts average 38% of those in the ‘UK service area’. Case studies of thundery periods highlight daily differences. The new annual counts offer a more accurate estimate of the lightning risk facing the UK population. For the period 2008–2016, one lightning death occurred, on average, per 59 000 lightning counts, and one person was either killed or injured per 4000–5000 counts.
