Damage Assessment for Performance-Based Design of

This paper summarizes research in which the damage evolution of rectangular concrete-filled steel tube (RCFT) members, connections, and frames, was documented using results from experimental tests from around the world. Two types of damage indices were then defined and used for each type of RCFT component to quantify damage.

Performance and calculations of recycled aggregate

This paper describes a series of tests on steel tubular short columns of circular section filled with normal concrete (NA) and recycled aggregate concrete (RAC). Twenty-two specimens, including 11 small diameter of RAC-filled steel tubular (RACFST) columns named CA series and 11 larger diameter of RACFST columns called CB series, were tested to research the influence of variations in

Design and Construction of Concrete-Filled Steel Tube

The concrete-filled steel tube (CFT) column system has many advantages compared with the ordinary steel or the reinforced concrete system. One of the main advantages is the interaction between the steel tube and concrete: local buckling of the steel tube is delayed by the restraint of the concrete, and the strength of concrete is increased by the
