Hysteretic Behavior Study of K-Shape Eccentrically Braced Steel Frame under Cyclic Loading

Abstract:

The seismic performance of K-shape eccentrically frames were researched by cyclic loading test method, in order to understand earthquake performance, stiffness degradation and dissipation mechanism of energy. It can be concluded that K-shape eccentrically frames provide high elastic stiffness and demonstrate excellent energy dissipation capacity in the plastic stage, the different length of the link beam of different layers has great influence on the energy dissipation capacity of the structure, when shear yielding of link beam occurs, stiffness degradation become apparent, the hysteretic curves were plump in shapes. Therefore, K-shape eccentrically frames have better hysteretic behavior and energy dissipation capacity, the results can provide a reference for the engineering design and related research.
