Design Analysis and Application of Large Cantilever Portal Pre-stressing Cap Beam Support
This article takes the Du'an Expressway project as an example and takes the Yanlang Bridge project as the background.The"steel pipe column+Bailey beam"bracket cast-in-place method is used to solve the problems of large span,high section,and large volume of large cantilever portal prestressed cover beams.At the same time,finite element analysis software is used to simulate the strength and stiffness of the bracket structure,and the equivalent weight preloading method of the bracket is adopted.The results indicate that the bracket system is safe,reliable,and economically feasible,which can provide a reference for bracket selection for similar projects.
