EXPERIMENTAL STUDY ON FOUR-SPAN RAHMEN BRIDGE WITH SLIDING-TYPE SEISMIC ISOLATION FOUNDATION
In this study, the oscillation behavior and aseismicity of a 4-span Rahmen bridge with a sliding type seismion foundation are investigated using model vibration experiments and numerical simulation. Built on Type III ground, the bridge is erected to 1/10 scale with a sliding-type foundation that was made by separating the footing in the horizontal direction, whereas conventionally piers and foundation structures are rigidly linked together. Teflon (PTFE) was inserted between the separated sections as the sliding interface material. The study results show that a sliding-type seismic isolation foundation has a significant positive effect in decreasing responses during earthquakes and the experimental results can be explained by the dynamic analysis.
