| Research Abstract |
Recently, seismic retrofitting has become increasingly important for seismically weak structures. This study aims to develop a new joint element which can be used in various structures and to construct of a shear strength formula as well as a mechanical model of the proposed joint element.
In this study, I developed new joint element which is consisted of a steel disk and an anchor bolt. The shear tests were conducted using the proposed joint element. As a result of tests, the proposed joint element has higher shear strength and higher shear stiffness than post-installed anchors which are used in usual seismic retrofitting. In addition, I constructed the shear strength formula and the mechanical model based on the failure mode of the tests.
