Performance Study On Steel-concrete Composite Floor In Light Weight Steel Structures Of Building

Light steel structure for the development of residential building construction in our country to achieve industrialization and industrialization have a catalytic role.Therefore, the reach of light weight steel structures of building is necessary, floor structure system is component which bearing vertical load, have a very important position. Appropriately designed floor is very important for induce the self-weight of structure and construction cost. It is contribute to early realization of industrialization of building in our countryThis paper study on the performance on steel-concrete composite floor in light weight steel structures of building. Light steel - concrete composite floors are cold-formed or cold-formed with sheet metal components and concrete combined and worked together to form a structure. This paper introduce the concept of light weight steel structures of building, and discusses the combination of light steel floor used in standard developments at home and abroad. Research was conducted on a combination of light steel structure, residential floors of a form of binding assay, the combination of slab cross-section positive flexural capacity performance. Their outstanding issues have been studied and discussed. Analysis of test results showed that this combination can be used as a light steel floor plate assembly for residential flooring applications. This combination of light steel frame floor and part of ceramsite concrete precast in the factory, and reinforced concrete poured at the construction site for the second layer, fully meets the requirements of steel structure on site. This saves on project costs, and reduces pollution caused by the industrialization of the residential development trend.
