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.
Highlights
According to Article 73 of the Construction Law, a structural failure of building means unintentional, violent destruction of a building or its parts and structural components of scaffoldings, shape-forming components, sheet piling and excavation support. [1,2,3] Structural failures of buildings are often tragic
The analysis shows that structural failures that are not the result of human mistakes constitute 12-60% of all
From the standpoint of the possibility to eliminate or at least minimize the frequency of occurrence of structural failures, the failures were analysed according to two different criteria: − building’s life cycle, − type of construction works carried out, The first criterion concerns the building’s life cycle
Summary
According to Article 73 of the Construction Law, a structural failure of building means unintentional, violent destruction of a building or its parts and structural components of scaffoldings, shape-forming components, sheet piling and excavation support. [1,2,3] Structural failures of buildings are often tragic. The District Building Supervision Inspector is responsible for qualification of a structural failure in case of sudden destruction of the building (structure) or its parts (even without fatalities), organizing a commission and an investigation in order to explain the causes and consequences of the damage during the accident [4]. The tools / methods used belong to the group of methods used in TQC [5] They are used to collect and process information, to supervise and improve. TQC tools are mainly used for [5, 7]: − creating ideas, − description and analysis, − identifying threats and problems, − identification and analysis of causes − identification and choice of solutions, − implementation and evaluation of effectiveness. The quality management tool (Histogram and Pareto chart) was used for the purpose
