RESEARCH ON CONSTRUCTION ACCURACY OF LONG-SPAN DOUBLE-CURVED STEEL ARCH
The study conducted relevant analysis using large-scale comprehensive venues as an example.The large-span steel truss shaped arch at its north main entrance and exit uses 270 tons of steel.The arch structure is mainly composed of two main members forming the upper chord of the arch,and is evenly suspended from the low-er chord by a combination of pipe trusses,forming the overall outline of the structure.The highest point of the arch is flanked by box shaped intersecting bodies that intersect orthogonally and diagonally on both sides.Factors such as the intersection of multiple arched members,intersecting welds,welding stress concentration,precision control during construction,and the influence of loads on structural deformation can all affect construction accuracy.Doing a good job in precision control is the key to doing a good job in this project.
