Abstract

Efficient use of materials in the tied arch bridge can be reach by optimizing it. This article examined initial arch angle and the top height effects. The use of initial angle (20°, 25°, 30°) combined with different top arch height (0,5 – 0,6 meter) is based on rise-span ratio 1:8 – 1:6,67. 9 bridge models are produced from these variations. This study aimed to minimizing deflection and weight for optimizing structural performance, thus decrease steel use also CO₂ emissions for support Indonesia toward SDGs 2045. 3D model was analyzed using FEM (Finite Element Method) Software with a 250 kg mid-span load using the tributary method, which is simulating pedestrian weight transferred through the floor plate and tie chord. Analysis results showed that the arch initial angle and the top height affect the structural performance. With the best performance is showed by type 1.3 with 20° initial angle and top arch height (0,6).

Abstract

Tied-arch bridges are bridges that have high structural efficiency, but are prone to bending instability. This study aims to analyse the relationship between arc geometry variations and the bending stability of tied-arch bridges using the Finite Element Method (FEM) based on SAP2000 software, employing both linear and non-linear approaches. The linear analysis results show that lateral arch deformation occurs, indicating the potential for global lateral instability of the arch. Meanwhile, the non-linear analysis, which considers the significant geometry effect (P-Δ), produces a bending capacity of 7.43-11.69 kN with a maximum deflection of -0.52 mm. Variations in the arch angle were found to affect the critical bending capacity without significantly impacting global deformation. These findings are expected to serve as a valuable reference for designers and structural engineers in determining optimal and efficient arch designs.
