Abstract

Owing to high strength and good ductility, steel structures are widely used in the construction of building frames in seismically active areas. This paper reviews the state of-the-art in testing, finite-element analysis and design of composite structural systems. Development of guidelines and recommendations of beam–column connections and moment frames are presented and a future research on composite structural systems is provided. In this paper, the effect of composite action on the ductility performance of the connections is reviewed through a series of large size experimental and analytical studies of beam-to-column sub assemblies. The studies presented in this paper highlights important behavioral observations and trends, some of which point towards the need for further consideration and refinement of current design procedures. The reference structure as well as the design procedures and assumptions adopted are discussed. This paper briefly describes some past experimental and analytical research on traditional connections relevant to the innovative types of connection models to be developed. This paper does not intend to provide a complete and systematic literature search on the topic but rather just present some examples of how connections have been investigated in the past.
