Abstract: Large-diameter concrete-filled steel tube (CFST) arch bridge transverse braces adopt self-compacting concrete to avoid laitance and air void defects. However, several old CFST arch bridges in China use ordinary concrete, ...

Abstract: Until recently, ordinary concrete has been used to construct concrete-filled steel tube (CFST) arch bridges in China, which has resulted in the formation of circumferential gaps around steel–concrete interfaces. Furthermore, ...
