Abstract

The chapter studies the cyclic behavior of self-consolidating concrete (SCC) filled hollow structural steel (HSS) columns. The test parameters include sectional types, the strength of concrete and steel, and the axial load level. Eighteen self-consolidating concrete filled hollow structural steel (SCCHSS) column specimens, 10 with circular sections and 8 with square sections are tested under constant axial load and cyclically increasing flexural loading. It is found that, in general, SCCHSS columns exhibit very high levels of energy dissipation and ductility, particularly when subjected to high axial loads. The features of SCCHSS columns under constant axial load and cyclically increasing flexural loading are similar to that of normal concrete-filled HSS columns.
