Event tree analysis to prevent failures in temporary structures

In this study, we examined the enabling and triggering events that caused failures in temporary structures. Using event tree analysis, we then analyzed the propagation of component failures. The concept of fuzzy sets is used to manipulate human-based subjective judgments, which are abundant during the construction of temporary structures, and to minimize the complexities of conditional events in the trees. Ranking of critical paths, based on the highest probability of failure, is also presented for quality control purposes.
