摘　　要：无比钢结构是一种新型的轻钢龙骨体系,我国现有的结构软件无法直接对其进行设计和计算,采用有限元方法是目前进行结构分析较好的选择。介绍了无比钢结构的组成及做法,提出了整体结构的有限元建模方法,并以5层教学楼为例,采用ABAQUS软件包分析了结构在风载和地震荷载作用下的水平位移,且与规范要求的最大值进行了比较。结果表明,按所提出的针对无比钢结构的有限元建模和分析方法,在风载和地震作用下计算得到的多层无比钢结构的层间和顶点水平位移均可以满足规范要求。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.
