Experimental behaviour of steel beam to concrete-filled steel tubular (CFST) column connections after exposure to fire

Publisher Summary The chapter describes the experimental behavior of a steel beam to concrete-filled steel tubular (CFST) column connections after exposure to fire. CFST columns have several structural and constructional benefits, such as high strength, fire resistance, large stiffness and ductility, restraint to local buckling of the steel tube provided by the infill concrete core, and omission of formwork, and thus reducing the construction cost and time. These advantages are recognized and have led to the increased use of CFST columns in some of the recent tall buildings in China. The chapter discusses some new test data pertaining to the behavior of steel beam to CFST column connections using external ring after exposure to the ISO-834 standard fire.
