Design of safe timber structures - How can we learn from structural failures in concrete, steel and timber?

Frühwald, Eva LU and Thelandersson, Sven LU (2008) World Conference on Timber Engineering, 2008
Abstract
During recent years, several spectacular collapses happened in large timber structures and the question is what can be done to prevent future failures. The main hypothesis for this project has been that quality assurance, control systems and improved training may be necessary, since the unwanted events are primarily related to human errors. A survey of failures in 127 timber structures has been made and results with an analysis of the underlying causes and associated conclusions and

recommendations are presented. The most common failure causes are poor strength design (41%), poor principles during erection (14%), on-site alterations (13%) and poor design with respect to environmental actions (11%). Wood quality, production methods... (More)

cause a small part (together about 11%) of the failures. The problem is therefore not the wood material, but designers and workers in the building process. (Less)
