Load path of a truss bridge

WitrynaWhen the bridge is to be built in seismic zone or earthquake zone, earthquake loads must be considered. They induce both vertical and horizontal forces during … WitrynaThe two alternative load path plans changed the stress in the truss girder with the losses of chords A8-A9, A29-A30, A44-A45, and A59-A58’, as shown in Figure 6 . The maximum principle tension and compression stresses increase significantly in the truss girder, caused by failures in chords A8-A9, A29-A30, A44-A45 and A59-A58’.
