Analysis of causes of structural failures of buildings using TQC tools

Abstract

This paper analyses structural failures of buildings over a period of ten years. Particular attention was paid to the analysis of structural failures caused by human mistakes. The analysis was performed according to two criteria: the stage of the building‘s life cycle and the type of works conducted in the area of the building site. The analysis was performed using a quality management tool (histogram and Pareto-Lorenza diagram), which allowed for identification of the causes responsible for the highest number of events. The analysis showed that three causes account for 64,61% of the structural failures that occurred.
