Abstract
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.关键词
