Fz. Yao et Ro. Foschi, DURATION OF LOAD IN WOOD - CANADIAN RESULTS AND IMPLEMENTATION IN RELIABILITY-BASED DESIGN, Canadian journal of civil engineering, 20(3), 1993, pp. 358-365
This paper summarizes some Canadian experimental results for duration
of load effects in wood, and discusses the theoretical framework utili
zed for their interpretation and implementation in design guidelines.
The theory is based on a model for accumulation of damage, and it is u
sed in the context of reliability assessment of a structure under load
over its service life. The paper also compares results from other the
oretical approaches. Finally, the background to currently recommended
design adjustment factors for duration of load is discussed.
