초록

This study aims to assess the shear ability, ductility, and energy dissipation characteristics of specimens intended for jacket application, utilizing the wrapping method. The two specimens include the moment frame and the composite plate frame with a wrapping jacket. The experiments were conducted under the condition of simultaneous application of axial load and transverse force. The experimental results reflect various seismic resistance abilities of a structure, such as story-displacement ratio, stiffness, energy dissipation, and plastic rotation. Additionally, the results reveal the distribution of cracks and failures in extreme stages.
