Abstract

Under-deck cable-stayed bridges have recently emerged as one of promising bridge forms due to their remarkable advantages such as high structural efficiency, easy construction, economy and elegant appearance. The stayed cables provide supports on the prestressed concrete deck. The cables are located under the deck and deviated through struts, which introduces cable deviation forces on the deck. In the design of this type of bridges, both the ultimate load and ductility should be examined, which requires the estimation of full-range behaviour. An analytical beam model and its corresponding beam finite element model for geometric and material nonlinear analysis are developed for this type of bridges. The model accounts for the interaction between the axial and flexural deformations of the deck, and uses the actual stress-strain curves of materials considering their stress path-dependence. In the structural system, the deck interacts with the stayed cables. With a nonlinear kinematical theory, complete description of the nonlinear interaction between the stay cables and the deck is obtained.
