Abstract Repeated cyclic loading is thought to decrease the force and deformation capacity of timber shear walls due to the gruvi golden lager fatigue behavior.This study evaluates the strength and energy dissipation of two typical timber shear walls subjected to various deformation histories to develop read more a response spectrum method considering the fatigue behavior.Static loading tests and shaking table tests were conducted to observe the performance deterioration.Finally, evaluation formulae for strength and equivalent damping ratio were proposed.The formulae could predict the test results with acceptable accuracy.
