The seismic response of a hybrid stress-ribbon vehicle bridge with a span-length of 400 m was numerically analyzed in the time domain. The adjusted acceleration wave record of the Hyogoken-Nanbu Earthquake was input into the model. In this model, a bilinear stress-strain curve was assumed. The findings revealed that the maximum normal stress in the upper and lower cables was in the range of the elastic region and that the maximum stress of combined bending moment and normal force in the edge girders was also in the range of elastic region except for several segments close to the abutments where the elasto-plastic stress was induced. Also, the maximum acceleration on the deck in the direction along the bridge axis was about 1.4 times larger than that of the input motion.
