Design of Arch-deck Connection in Long-span Network Tie Arch Bridge
The Qilu Yellow River Bridge is a through tie-arch bridge with spans layout of(95+280)+420+(280+95)m.Inward inclined arch ribs with pentagonal steel box section and orthotropic composite deck are designed.Arch-deck connection is different from the traditional one due to the complex sections and arch rib space curve,and the force transmission path is complex.Detailed design is made for the special arch-deck connection,and finite element model is built to check the structure safety of this part.Calculation results show that the designed arch-deck connection can ensure the smooth and reliable force transmission.Except for the local stress concentration,the stress of the main load-bearing plates meets the design requirements.
