Reasonable Structural Design Analysis of Large Cantilever Composite Beam With Less Stiffening Beam
With the advantages of steel bridges and composite bridges becoming more and more prominent,the application of large cantilever cross-beams is also more and more.This paper takes the design of large cantilever cross-beams of a bridge in Fuzhou as an example,a large general-purpose finite element software Ansys is applied to establish the spatial plate and shell model of the steel-concrete composite bridges,analyzes the force performance of the cross-beams with different stiffening arrangements,compares the stability of the cross-beams webs with different specifications,and arrives at some suggestions on the design of large cantilevered composite cross-beams with fewer stiffeners.
