Outline of Final Research Achievements |
For the effective use of building stock in our matured society, a retrofit devise of existing steel frames with consideration on business continuity during construction and building space usage was developed. The named minimal-disturbance retrofit damper enhance the seismic capacity of the frames through the intensive reduction of the force and deformation demands at the frames' vulnerable components. The method also cap the increase of the frame' strength to avoid damage propagation to the un-retrofitted parts. The study evaluated the deformation reduction performance at the vulnerable components, i.e. beam ends, by large-scale structural tests and numerical analyse. In addition, a design method that is suitable for the retrofit method were proposed and its effectiveness was demonstrated through structural tests and numerical analyses. The research results were published in five leading international SCI journals, two peer-reviewed domestic journals.
