This research aims to model a reinforced concrete bridge structure with PCI Girders and a single pier based on a scaled prototype of a hollow square reinforced concrete bridge pier made of high-strength steel, adhering to similitude concepts in both geometric and kinematic aspects. The motivation for this research stems from the increasing interest in hollow bridge piers to reduce concrete usage and the potential for using high-strength reinforcement steel in piers, which is currently limited. The research begins with scaling the prototype pier to set the dimensional boundaries for the full-scale bridge model. The bridge's functions and constraints are determined through an iterative process to achieve a realistic and compliant bridge configuration. The design process starts with preliminary stages followed by modeling using Midas Civil software for structural analysis. Bridge element design is conducted manually based on prevailing regulations. The study concludes that the designed structure can withstand service loads and seismic forces, evaluated for the Bandung Regency location with an SD site class. However, the full-scale pier dimensions and reinforcement do not meet the confinement reinforcement requirements, which were disregarded in this study as the moment-curvature capacity of the designed pier was not evaluated.
