Abstract:

Taigu Wei River Bridge is located at Daima group in Baoji, and is an important channel connecting the north and south sides of Wei River. The main bridge is a through continuous butterfly arch beam composite structure. The arch ring is a composite butterfly arch ring with the unique shape and complex force. The design thought and force characteristics of the bridge are mainly introduced, and the modeling analysis and calculation are carried out for the overall and local structures.

Key words:butterfly arch; multi-span continuous beam; arch beam composite system
