Research Of Calculation Method Of Composite Wall In A New Type Of Light-Gauge Steel Joist System

Web Light-Gauge steel joist system (Web steel) is a new type of steel structure, coming from Canada with such many advantages as light weight, higher standardizing, assigning space flexible, good performance of the seismic resistant, industrialization producing, short Construction period, protecting environment and economizing energy sources etc. This kind of structure has been used mostly in low story residential building for 20 years in North America. It agrees our national estate policy applying Web steel to multiple-story residential building. Web steel has a good future in China.Web steel is composed of small trusses and has complex constitution, sheeting diaphragms effect must be considered. There is no design software and code for this kind of structure. Testing and analysis are needed.A series of testing research and finite element analysis were done in Wuhan University of Technology for the Web steel truss beam, truss column, wall and joint. A multi-storey Web steel building was designed. The research work was provided as a reference for the popularization and application of Web steel in China.Taking Web steel wall as the research object in this thesis, two calculation methods of web steel wall under lateral loads are provided. A series of finite element analysis were done. This thesis covers following contents:1. ABAQUS software is introduced and the building techniques of two finite element analysis models of WEB steel wall are provided base on ABAQUS 6.4 software.2. Several web wall models are built and analyzed base on above techniques. The finite element analysis results have a good accordance with the experimental data, showing the calculation methods are reliable and valuable.3. Two buildings are taken as an engineering example, the horizontal displacements and Von.Mises stresses of four typical web steel walls under the wind load and earthquake are analyzed using ABAQUS 6.4 software, which are compared with the code values. The analysis and comparison results prove the simplified building methods of Web steel wall finite element model present in this thesis are valid.
