EXPERIMENTAL STUDY ON LIGHT STEEL FRAME UNDER CYCLIC LOADING

摘要

Multistory light steel frames have been used in multistory buildings in China, as they have lots of advantage. In order to study they seismic behaviors, a low-cycled reverse loading experiment on a light steel frame of two stories and two spans has been completed. The hysteretic behavior, energy dissipation, rigidity degradation, failure mechanism, etc. are studied. The results indicate that light steel frames perform good seismic behavior. The dissipation capacity of panel zone is well.
