Diagonal arch bridges exhibit unique structural behavior due to their asymmetrical hanger arrangements and complex dynamic interactions among the arch, girders, and hangers. While conventional pinned–roller supports are widely used for their simplicity and cost efficiency, their high horizontal stiffness leads to shorter natural periods and greater seismic demands. To enhance seismic performance, this study investigates the use of lead rubber bearings (LRB) as an alternative support system and evaluates their effects on the dynamic characteristics of a diagonal arch bridge. Using the Detail Engineering Design (DED) of the Mungkid Bridge in Indonesia, two finite element models were developed in Midas Civil 2025: one with conventional pinned–roller supports and another with LRB isolators. Modal analysis was conducted to determine natural periods, mode shapes, and mass participation. Results show that incorporating LRBs lengthens the bridge’s fundamental period by up to 182% compared with the simple-support configuration, effectively reducing natural frequencies and seismic acceleration demands. The LRB model also concentrated modal mass in the first few modes, enabling clearer identification of dominant vibration mechanisms. Although the isolators introduce greater flexibility and improve seismic resilience, further nonlinear time-history analysis is recommended to capture hysteretic effects. These findings highlight the potential of LRBs to improve the seismic adaptability of diagonal arch bridges
