“…Li et al [8] studied the longitudinal seismic susceptibility of a ve-span high pier cable-stayed bridge using the susceptibility method. Yan et al [9] found through experiments that ductile design with plastic hinges on the tower column, i.e., strong pole and weak tower column design, is another e ective seismic design strategy, and the residual displacement at the top of the tower column is small even under very strong seismic excitation. Tonyali et al [10] studied the random response of cable-stayed bridges under spatially varying ground motions in the case of local soil and variable wave velocity.…”

Due to the small self-weight of the steel truss cable-stayed bridge with a single tower and a single cable plane, the torsional stiffness and wind stability of the structure are reduced. The arrangement of the deck type makes the mechanical properties of the cable-stayed bridge more complicated while reducing the cost and increasing the aesthetics. The effects of structural parameter variations and traveling wave effects on the seismic response of this steel truss cable-stayed bridge with a single tower and a single cable plane were investigated by the nonlinear time-history analysis method and nonuniform seismic analysis method. The results show that the displacement of the floating system under seismic action is larger than the other three systems, but its internal force is significantly smaller than the other three systems. The spectral characteristics and the duration of ground shaking have a greater influence on the maximum bending moment values corresponding to the height of the cable tower and the maximum axial force values of the main girder bars corresponding to the length of the bridge under earthquake action. The effect of steel truss girder stiffness parameter variations on structural internal forces of bridges and the effect of traveling wave effects on structural displacements of bridges in specific apparent wave velocity intervals do not exist universally.
