Abstract: Elastic finite element analysis for steel frame with concrete infilled wall which is with opening is performed in this paper. The deformation and distribution of stress under mono-loading are achieved. For the purpose of simplifying the calculation during project design, the model of cross steel brace is introduced to simulate the properties of the infilled concrete wall. The results are achieved through comparing the results of the models, such as the solid model with whole infilled wall, solid model of walls with opening, model of crossed steel brace, model of steel frame without braces. Some conclusion and suggestion will be given.
Keywords: steel frame; infilled reinforced concrete wall with opening; finite element analysis; crossed steel brace
