Development of accident analysis for civil engineering structures an AcciMap diagram for collapsed steel dome structure

Abstract

Accidents in the construction sector are often the subject of studies on work safety. These studies mostly focus on fatalities and injuries. However, accidents cause problems concerning construction processes as well. Accidents leading to structural collapses are an important subject that should be examined in this respect. These collapses can result from numerous causal factors. Therefore, a comprehensive accident analysis outlining the causes of steel structure collapses during construction is needed. This paper has 2 p.m. and the first is to determine the relationships among the causes of steel structure collapses using the six fundamental levels of AcciMap. The other purpose and the subject that makes the study novel is to show together causal factors that exist both during and before construction. In this context, the accident causality factors of a steel dome structure that collapsed during construction were determined by expert consultations. Based on expert evaluations, a Pareto analysis was conducted to identify the factors that contributed most significantly to the collapse. Among the 33 causal factors identified for the collapse, 15 were found to have existed pre-construction. Thus, one of the findings is that the chain of errors during construction is due to some systemic factors before construction. This study contributes to the literature by providing a framework for preventing accidents during the construction phase of steel structures.
