Bond behavior in concrete-filled steel tubes
WebPrevious studies have proven that concrete-filled tube (CFT) systems can significantly enhance the mechanical properties and durability of encased concrete; CFT has emerged as one of the essential strengthening forms for high-rise and pile foundations [1,2].In particular, concrete-filled steel tube (CFST) and concrete-filled fiber-reinforced … WebThis study aims to investigate the bonding performance of push-out tests conducted on self-compacting rubberized concrete-filled steel tubes (SCRCFST). The rubber content, particle size, interface bonding length, and water–cement ratio were varied to evaluate their impact on bond strength. The failure mode and failure mechanism were analyzed.
