An overwiew of failures in large-span timber structures
SP - Sveriges provnings- och forskningsinstitut, Trätek.
2006 (Swedish)Report (Refereed)
Abstract [sv]

A total of 18 failures (collapse, crack formation, excessive deformation etc) in Swedish timber structures from the period 1978 - 2005 were reviewed. The most common reasons for failure was found to be the lack of design or poor design in relation to mechanical loading, which was the primary cause of failure for nine of the cases. In these cases the presence of notches and holes, at which the high stresses perpendicular to grain develop, was often the main cause of failure. In six of the eighteen cases it was concluded that the failure was caused by errors done in the manufacturing of the product (mainly glulam). Examples of this category include, for example, gluing errors (lack of hardener, poor gluing pressure etc.) The main conclusion from the investigation is that in none of the cases was the wood raw material the cause for failure. Instead, all failures were either due to the lack of knowledge (lack of design knowledge, lack of knowledge about sound production methods) or due to poor quality control procedures. Key words: timber structure, failure, collapse, glulam, glued laminated timber, wood, wood products
