초록
In this study, MIDAS Civil was used to perform nonlinear static analysis on bridge piers, followed by time-history analysis after applying seismic isolation devices. The results revealed that as the height of the piers increased, structural capacity and strength decreased, while the required capacity increased as the ground weakened. Additionally, lead-rubber bearings demonstrated superior performance compared to friction pendulum bearings in terms of displacement, shear force, and moment in both the bridge axis and pier directions. Furthermore, it was found that seismic waves have different impacts depending on the natural frequency of the structure, highlighting the need to consider various seismic waves during the design phase to ensure structural stability. The study also confirmed that seismic performance decreases with increasing pier height, emphasizing the necessity of reinforcement in the design.
