Multi-storey Steel Structure Residential System And The Performance

In the "Tenth-Five-Year Program " of the Steel Structure Industry of China and the Compendium of the Developing Layout before 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 structure in order that the development of the national industry of steel structure climb up to a new stage.The paper sum up residential building system of multi-story steel construction. Introduce main structure systems of steel residential building, including framed-structure, diaphragm-braced framed-structure, truss-structure. Afterward the paper discuss five aspects for architecture system, main component, node dispose, light weight walls and fireproofing in turn.Meanwhile this paper research the capability of framed-structure in multi-story steel residential building. 2000 case for different span, floor highness and section of columns or beams have been computed by ANSYS. Base the result of solution, we discuss the effection of beam and column's section to structure displacement. And then draw curves between span, floor highness and average steel consume. Finally the paper conclude that in multi-story steel residential building, traditional structure form as small span and room was not aptitude, and command forms of big span and room, which both able to utilize steel structure and can meet tenement' requirement of freely room.
