Research Of Light Steel Structure Residential System

Multi-layers steel structure residence have following excellent performances:fast construction,high industrialization,high economic and technical index,good anti-seismic capability.Steel structure residence has natural advantage,as well as productive policies in our country at present state.Although a series of multi-storey and high steel structure residence has being built for test,but the structural system must be got further research and performing.The thesis divides three parts of contents.First;use of software ANSYS to calculate and analyze structural system of multilayer light steel residence under static load,light steel structure system for residential use H section steel column and concrete-filled tubular steel column in structure systems of steel frame structure and steel frame-support structure.Study force performance and resist sidesway performance of the structure systems,and compare the carrying capacity?deformation performance and economic performance to structural systems so give the economy total steel quantity of systems.Second;use time-history to analysis power performance and characteristic of structural system for multilayer light steel residence in earthquake action,and compare response of time-displacement with different parts of the structure systems.Third;carry out the test of light weight floorslab(rectangular steel tube-light weight concrete floorslab),and to test their deflection and largest bearing capacity.finally get inferential computing formula.In this paper,through a series of calculations,comparison and analysis,which structural system should be selected for steel structure residence at present got further research.To prompt development and popularity of steel structural residence,the findings will take a certain role of instruction and referenec.
