Hangbu River Bridge is the city of Hefei Chaohu tourist road across the Hangbu River main project. It is a prestressed concrete cable-stayed bridge with single tower of main bridge span arrangement 130m. The main tower adopts steel-concrete composite structure of deck above the steel structure and fol owing the bridge concrete structure. High strength screw connection is used to Steel - concrete. The tower column of root stress is transfered to the concrete tower by tower base plate. And the tensile stress is transferred to the base through screw anchor. This paper mainly introduces the design of steel-concrete composite section of pylon.
