Abstract:: To study the anti-progressive collapse mechanism and failure characteristics of the CFST frame under the failure of key column, using the ABAQUS/Explicit analysis method,this paper developed a 3D finite element model this paper developed a 3D finite element model of CFST frame considering the full-height infilled walls. The material constitutive model of steel, concrete, infilled wall masonry and the restraint model between different components were selected reasonably.According to the actual working conditions, the horizontal tie-in effect at the end of composite beam was considered, and compared with the experimental data of existing researchers to verify the rationality of the modeling method.On this basis, the load displacement curve of CFST composite plane frame with infilled wall was calculated, and the local failure characteristics of infilled wall were analyzed,and compared with those of CFST composite frame, and the influence of infilled wall on collapse bearing capacity and failure mechanism of CFST frame was analyzed.Results show that, under the vertical load, the whole process stress mechanism of CFST composite plane frame anti-progressive collapse mechanism includes: beam mechanism, catenary mechanism and failure stage；the infilled wall could significantly improve the anti-progressive collapse bearing capacity of the CFST composite frame, the bearing capacity was more obvious in the beam mechanism stage. The bearing capacity of the infilled wall was mainly formed by the diagonal compression brace supporting. Therefore, it was suggested that the role of infill wall should not be ignored in the design of progressive collapse resistance of such structures.
