- Abstract
- In this paper, in case of two-span steel-concrete composite bridges strengthened by external tendons, an analytic expression for the increment of tendon force under external loads is derived using virtual work method for straight and draped external tendons and a new rating factor equation is proposed. Considering the proposed rating factor equation, an analytic procedure has been developed to calculate the number of tendons and the initial tendon force. This method is used to verify a validity and rationality for an existing two-span composite steel-concrete.
