ABSTRACT:

Concrete-filled steel tubular (CFST) arches with corrugated steel web (CSW) are a new developing type of arches, which combine the high strength of CFST and good shearing resistance of CSW. This paper studies the behaviour of CFST arches with CSW (or CFST-CSW arches) under in-plane and out-of-plane loading conditions. A series of experiments was conducted. The displacement and strain of CFST-CSW arch models under different loading schemes were measured. These experiments enabled the direct assessment of the load-deflection and failure mode of the CFST-CSW arches. The effectiveness of this new arch type verified by comparison of a reinforced concrete arch model with CSW in terms of the ultimate load and failure mode.
