Research on Influences of Deck Slabs on Stress of Steel Truss Beams of Suspension Bridges

ZHOU Yanqi1,XIE Yujie2,CHEN Lihua3  
Based on some steel truss beam suspension bridge in Chongqing as a project example,this paper comparatively analyzes the y values of neutral axis via three methods,i.e.calculation of sectional characteristics,Midas/civil modeling calculation and loading test and studies whether deck slabs participate in stress or not and their influences on stress of steel truss beams of suspension bridges.The results show that local deck slabs will resist bending together with truss beams when girder downwarps under the effect of live load,enabling neutral axis in integral of girder to move upwards,the stress on upper boom decreases dramatically,while the stress on lower boom increases greatly.This result can provide a reference for similar projects.
