抄録

A new aseismatic reinforcement method for existing over-track station buildings has devised. In this method, we can reduce seismic response of the building to improve relative aseismatic performance using extension structures expanded in work for accessibility improvement carried out simultaneously. It can cut reinforcement work volume as well as reduce costs and construction time. In the model case,we evaluated aseismatic performance of the building of the applicable project by response analysis. The evaluation results demonstrated that coupling with an added vibration system that has dampers demonstrates remarkable response reduction effects.
