FINITE ELEMENT ANALYSIS TECHNIQUE OF HORIZONTAL DISPLACEMENT WEB LIGHT-GAUGE JOIST STEEL SYSTEM

WEB light_gauge steel joist system(WEB Steel) is a new type of light steel structure.Because the current structural software in China can't be directly used to design and analyze this kind of structure,the Finite Element Method is the suitable method for the structural analysis of WEB Steel.The structural composition and construction of WEB Steel are introduced and the building technique of finite element model is provided.Taking a five-storey classroom building as an example,the horizontal displacement of the building under the wind load and earthquake was analyzed using ABAQUS 6.4 software,which was compared with the code value.Based on the simplified building method of finite element model,the inter-storey and top horizontal displacement can be smaller than the code values for the five-storey WEB steel building under the wind load and earthquake.
