Research on the Joint of Concrete-Filled Steel Tubular Column and Steel Beam

Ying Zi Yin, Yan Zhang

Open publisher page 5 citations

Abstract

With the pseudo-static test of 4 concrete-filled square steel tubular column and steel beam joint with outer stiffened ring, this paper discusses the failure characteristics, failure mechanism and seismic behavior of joints under different axial compression ratio. The analysis of the testing results shows: when reached the ultimate strength, the strength degradation and stiffness degradation of joints are slowly and the ductility is also good, the energy dissipation capacity of joints is much better.
