Abstract: Subassemblage tests were conducted on the panel zone within steel beam-to-concrete filled steel tube (CFT) column moment connections made from high-strength material to investigate their elastoplastic behavior. The writers ...

Abstract: In the design of beam-to-column subassemblies in concrete-filled steel tubular column systems, a design formula established by the Architectural Institute of Japan (AIJ) is applied. However, in the current AIJ standard, ...

Abstract: The behavior of concrete-filled circular and square steel tubular (CFT) beam columns with a variety of material strengths was investigated experimentally. The main test parameters are steel strength (400, 590, and 780 MPa), ...
