Load duration behavior is one of the most significant effects distinguishing timber materials from other structural materials. The stochastic damage accumulation process has been investigated. Safety assessments of structures built in the past require taking into consideration many different parameters. These parameters are mostly random and describe materials characteristics, actions and history of actions. The load bearing capacity of timber structures decreases with time. It depends on the type of load and timber. Strength reduction effects, referred to as creep-rupture effects, due to long term loading at high stress ratio levels are known for many materials. Timber materials are highly affected by this reduction in strength with duration of load factors.
