Cyclic behaviour of concrete filled steel tubular column to steel beam connections

摘要: An experimental investigation into the behaviour of composite column-to-beam connections using ten large-scale has been conducted, four under monotonic loading and six cyclic loading. This paper presents details results tests. Details from tests are reported in a companion paper. All consisted concrete-filled steel tube (CFST) column (circular), compact universal beam section shop fabricated connection stub. Monotonic testing was first carried out results, were used to conduct Each specimen tested cyclically had same general form, consisting direct wall (using flange plates, web cleat plates) reinforcing bars welded top bottom flanges, embedded concrete core. It found that provided face capacity force hinge itself, behaved very stable fashion, achieved ductility levels which only limited by nature test itself.
