Stiffness degeneration indicates the decrease in stiffness with different loading cycles at each load step. The ring stiffness method is used to analyze the stiffness degeneration [7,16], which can be expressed as Ki=∑i=1Pji∑i=1nΔjiwhere Ki is the ring stiffness, Pij is the peak load for the ith loading cycle at the jth displacement ductility ratio, Δij is the corresponding peak displacement for the ith loading cycle at the jth displacement ductility ratio, and n is the cycle number.

This study aimed to investigate the seismic behavior of simply supported steel–concrete composite I beam and box beam through a quasi-static experimental study. A total of 22 composite beams included in the experiments, and parameters including shear connection degree, transverse reinforcement ratio, longitudinal reinforcement ratio, section type, diameter of stud, and web thickness were investigated. Based on the test, hysteretic response, skeleton curves, failure mode, stiffness degradation, ductility, and energy dissipation were discussed. ...
