PERFORMANCE EVALUATION OF GLULAM MOMENT RESISTING JOINT SUBJECTED TO REPEATED CYCLIC LOADING

Fatigue behavior of glulam moment resisting joint subjected to repeated cyclic loading has not been well clarified. In addition, the accuracy of conventional design formulae for rotational stiffness and yield/ultimate moment should be discussed especially related to the method to obtain material properties. In this research, repeated cyclic loading tests were conducted for drift pined joints with insert-steel gusset plate and tensile-bolted joint. Deterioration of strength and energy dissipation is focused on. The dependency of the performance on the material properties is also investigated through sensitivity analysis.
