This paper will focus on aspects of the advanced analysis and underlying behavior of composite structures with concrete-filled steel tube (CFT) columns. Through a detailed examination of the results of a suite of full-scale slender CFT beam-column tests, insight into the cyclic behavior of such members is gained, specifically pertaining to local buckling of the steel tube and the plastic hinge ...

Damage evolution of rectangular concrete-filled steel tube (RCFT) column and beam-column members as documented in experimental tests is presented in this paper. An experimental database was first constructed that included RCFT tests available in the worldwide literature. Based on the experimental data, appropriate damage states for RCFT members, connections, and frames were defined at different...

The exceptional structural strength and low cost of steel-concrete composite columns make them a popular choice for civil engineering structures. Numerous forms columns, including steel tubes filled with concrete, have been produced recently in response to various construction situations. Cold-formed tubular concrete filling higher ductility due their capacity withstand inner buckling postpone ...

This paper aims to experimentally study the fire performance of steel-reinforced concrete-filled steel tubular (SRCFST) columns without protection. Eight SRCFST specimens with cruciform section profiled were tested under ISO-834 standard fire. The various test parameters including cross-section type tube (circular or square), load ratio and eccentricity considered discussed. temperature distrib...

Abstract Due to high bearing capacity and excellent seismic performance, the section steel reinforced concrete-filled rectangular tube has been widely applied in engineering. The application of stainless for outer can improve durability performance members. In this study, ABAQUS software was used perform nonlinear analysis on tubular columns, numerical model validated against experimental data....
