摘要	The traditional antiprogressive collapse design of the building structure mainly focuses on improving the bearing capacity of the beam mechanism and catenary mechanism for the upper beam connected failure column, while ignoring the capacity of existing nonstructural members to share the redistributed internal force after the key columns were damaged. To study the progressive collapse resistance of composite frame with CFST columns and fullheight infill walls under the middle column removal scenario, a 1 / 4scale twostorytwobay composite frame specimens were designed and tested. By monotonic static loading of the residual structure under the middle column removal scenario, the loaddisplacement relationship curves of the specimens, the global / local failure modes and the strain developments of critical locations were obtained. The experimental results show that the progressive collapse loading process mainly includes four stages, i. e., the elastic stage, the elasticplastic stage, the fractured development stage and the failure stage. The infill walls can increase the collapse resistance of the composite framed structure, but will reduce the ductility. Based on the test results, the refined finite element (FE) models using finite element software ABAQUS / Implicit were established to conduct the mechanism and parametric study, and to verify the rationality of the modeling method and constitutive relationships of concrete and steel. Furthermore, the progressive collapse resistance and failure modes for infill wall with different opening rates were analyzed. It is found that the opening rate has an apparent effect on the initial stiffness, peak load and displacement ductility of the specimen. The research results can provide reference for the progressive collapse resistance design of the composite frame structures. © 2022 Editorial Office of China Civil Engineering Journal.
