Reseach On Large Bay And Saving-emergy Of Multy-story Steel Structure Residence

In the"Tenth-Five-Year Program"of the Steel Structure Industry of China and the Compendium of the Developing Layout befour 2015(draft),it is referred that during the period of"Tenth-Five-Year Program",the national steel structure industry should lay emphasis on multi-story steel stucture in order that the development of the national industry of steel stucture climb up to a new stage.Firstly,The paper sum up residential building system of multi-story steel construction ,Introduce main structure system of steel residential building ,including framed-structrue,diaphragm-braced frame-stuctrue,truss-structure.afterward the paper discuss five aspects fou architecture system﹑main component﹑node dispose﹑light weight walls and fireproofing in turn .the essay analyzed the advantages and the disadvantages of the structure systemand choised the eccentrically braced frame. After that, Eccentrically braced frame have the advantages of both moment-resisting frames and concenrtically braced frames.The system can provide high elastic stiffness and large inelastic energy dissipation capacity in resisting lateral loads caused by seismic activity,So, applying the analysis of the influence of active beam link of eccentrically braced steel frame on anti-seismic capability of the structure is expatiated. Lastly,some relevant examples are presented about different lenghths of active beam link of eccentrically braced steel frame.then those examples are calculated by finite element analytical software ETABS8.4.8.after analyzing the results of calculating ,this thesis preents some conclusions which are applicable to structural designs...
