Axial behavior of concrete-filled double-skin tubular stub columns incorporating PVC pipes
This experimental study presents concrete-filled double-skin tubular columns and demon-strates their expected advantages. These columns consist of an outer steel tube, an inner steel tube, and concrete sandwiched between two tubes. The influence of the outer-to-inner tube dimension ratio, outer tube...
