Abstract:

Based on the requirement of parking, the three-dimensional parking structure with the alternation story-height energy dissipation truss lateral-load-resisting system was presented. The behaviors of the alternation story-height energy dissipation truss lateral-load-resisting system under low cyclic loading were studied by finite element method. Effects of the length of energy dissipation beam within the truss on lateral stiffness, load-carrying capacity, ductility and energy dissipation capacity of the lateral-load-resisting system were investigated. The results indicate that the lateral stiffness, load-carrying capacity, ductility, and energy dissipation capacities will decrease with increase of the lengths of energy dissipation beams. The energy dissipation capacity of shear-yield-typed energy dissipation truss is superior to that of bending-yield-typed one. However, the energy dissipation beam of shear-yield-typed energy dissipation truss should not be too short; otherwise, its energy dissipation capacity will be confined.
