Abstract

This paper analyses the failure of a bolt which sustained a scaffolding during a construction process. The work performed begins with the fractographic analysis of the failure section and continues with a structural integrity assessment using the European FITNET FFS procedure. The main conclusion is that failure occurred due to the superposition of an overloading which the scaffolding was not designed for and an environmental assisted cracking process.
