Abstract

Transportation is an integral part of social life. One of the structures that can support transportation is the bridge. The construction of the Semujur Bridge will be planned to meet and support transportation needs. This bridge is expected to be a new connecting bridge to cut travel time in Pangkal Pinang City. Semujur Bridge, with a width of 20 meters and a total length of 100 meters, is planned to use a steel arch bridge because the arch bridge can reduce the bending moment on the bridge. The bridge uses a box girder cross section because the arch bridge with a steel box cross-section is considered more economical and has higher flexural strength and torsional stiffness. Semujur Bridge will also have a diagonal arch. With the new construction design, it is expected to be a structurally strong bridge, both against earthquake loads and bridge dynamic loads. As a result, in this study, it was found that the longitudinal girder WF 600x300x14x23, transverse girder GIRDER 1500x400x30x30, tie beam BOX GIRDER2500x2000x40x40, and Macalloy 520 (M100) hanging cable with a diameter of 97 mm.

Abstract

ABSTRACT The bridge design modification presented in this study focuses on implementing a steel arch truss system combined with Fluid Viscous Dampers (FVDs) to improve structural efficiency and seismic resilience. The steel arch truss enables a longer main span with fewer intermediate supports, offering construction advantages, enhanced stability, and improved aesthetics. Additionally, the integration of FVDs aims to reduce structural displacements during seismic events, thereby minimizing potential post-earthquake damage.The object of this study is referred to as Bridge XYZ, assumed to be one of the key bridges in Gresik Regency, serving as a vital connection between Gresik and Lamongan. This bridge plays a strategic role in supporting mobility and logistics distribution in the region, making structural optimization and seismic mitigation essential. The research methodology includes data collection and literature review, followed by the structural redesign process. Structural modeling and analysis were conducted using SAP2000 software, adhering to Indonesian bridge and seismic design standards. The primary objective is to develop a single-span bridge configuration using steel orthotropic decks for a lighter superstructure and to evaluate the effectiveness of FVDs in reducing seismic-induced displacements. The analysis results show that the redesigned bridge utilizes BJ55 steel orthotropic deck plates with T-profile ribs, cross girders with WF profiles, tie beams with box girders, and Macalloy suspension cables. The application of FVDs successfully reduced seismic displacement by 3% to 45%, demonstrating their effectiveness in enhancing the bridge’s structural resilience.KEYWORDS Fluid Viscous Damper; SAP2000; Steel Arch Truss.
