ABSTRACT
ABSTRACT: In the high-rise steel structure buildings with bigger storey height and largespan, layer lateral ductility ratio does not meet standardize requirements limits, generally. In this paper, metal yield dampers in the beam and support node was proposed, and studied in an example of one training center for high-rise steel structure building, in order to control the structural the large interlayer lateral ductility ratio. And damper node design scheme was obtained. The calculation results show that the energy dissipation brace can effectively reduce the displacement response of the structure under seismic action and it can improve the seismic performance. It is contrast to ordinary steel support with good economy.
