“…Compared with steel joints and reinforcement concrete (RC) joints, rigid composite joints consisting of steel beams and RC slabs exhibit a higher load-carrying capacity and better deformation ability [4][5][6][7]. Furthermore, the reinforcements in the RC slab are essential components contributing to "catenary action", especially when the steel joints do not satisfy the rotation demand of catenary action [8].…”

This is the unspecified version of the paper.This version of the publication may differ from the final published version. Abstract: A partial damage caused by an abnormal load could trigger progressive collapse of high rise buildings which may lead to terrible casualties. However, in the process of column failure, "catenary action" plays an important role in redistributing the internal load and preventing progressive collapses of the structure. Rigid composite joints, thanks to their high strength and good ductility, exert great influence in catenary action. Therefore, an experiment related to a 1/3 scale progressive collapse resistance with the use of rigid composite joints was conducted, and the results of the experiment were analyzed. Based on the experiment results, a FE model was developed and analyzed. This paper describes the experiment, the results analyzed, and the FE model in detail. The experiment showed that the progressive collapse mechanism of composite frame consisted of 6 stages: elastic stage, elastic-plastic stage, arch stage, plastic stage, transient stage and catenary stage. In catenary stage, catenary action evidently enhanced the resistance to the progressive collapse of the frames. The steel-concrete composite frame with rigid connections designed in accordance to current design standards showed a good resistance to progressive collapse. It is also found that horizontal restraining stiffness of the frame exerted great influence on the resistance in catenary stage. Permanent repository link

“…This method which was proposed by Liew et al [17], is similar to Method 1 in the calculation of the stiffness of the steelwork, S s,ini . However, the initial stiffness of the entire composite connection, S j,ini was derived by adding S s,ini to the stiffness of the reinforced slab, S c,ini .…”
