Experimental Study on Flexural Behavior of CFT Girder-Deck Composite Section

A new bridge system described in this paper uses concrete-filled steel tube (CFT) girders as a replacement for conventional girders. Experimental investigations were carried out to comprehend the flexural behavior of CFT girder-slab deck composite section. The experimental investigation consisted of designing and constructing a test specimen and loading it to collapse in bending to check the applicability of the system. The test results showed that concrete filled steel tube girders have good ductility and maintain its strength up to the end of the loading. In the test, the flexural behavior of each specimen of CFT girder-deck composite section is identified.
