Existing outer-frame type seismic retrofitting cause problems of daylight, escape route and diminishing property values.
Authors propose that outer-frame type seismic retrofitting of Visco-Elastic Damper including Axial Force Transfer Mechanism Method solve these problems. This damper system has features that can bear sustained axial force and variable axial force, and focus shear deformation on Visco-Elastic Damper.
Authors confirmed performance of this damper system by biaxial loading tests, and verified the appropriateness of numerical analysis model for damper system.
