    Load duration effects with respect to long term decrease of strength are very important for structural timber. This report describes how the load duration effect can be determined on basis of simulation of realizations of the time varying load process. Wind, snow and imposed loads are considered and the stochastic models are formulated in accordance with the load models in the Danish structural codes, DS 409, and DS 410. three damage accumulation models are considered, namely Gerhards model, Barret & Foschi's model, and Foschi & Yao's model. The parameters in these moels are fitted using data relevant for Danish structural timber, Hoffmeyer.
