Design Technology of Lug Plate Connected with Larger Cable Force Suspender
There are many types of connection methods between the suspender of an arch bridge and the arch ribs and the main girder,among which lug sleeve anchoring system is commonly adopted.The reliability of the connection nodes is of great significance to the structural safety since the suspenders are functioning as the critical stress-bearing components of an arch bridge.A local finite ele-ment model is established for the lug plate,the cable force of which is relatively larger,to analyze the reliability of a practical arch bridge structure.The calculation results show that the adopted lug plate in the structure can meet the requirement for the cable force of approximately 400 tons.
