Abstract

The occurrence of changes in the location and height of the tide at the time of execution that exceed the planning conditions and disrupt the flow of municipal shipping. For this reason, the suspension bridge chamber was upgraded in order to create a traffic-free area opposite the free threshold. The results of the manual analysis taking into account the labor force due to the bridge steps, so that the real value of the bridge chamber is obtained to obtain the ideal deformation of the bridge working load. The ability of the bridge state to change the deformation results from this evaluation. The behavior of the four conditions was significantly different, namely the SDL forward state, in which the horizontal force that occurred in this state increased, but the deflection decreased by up to 200%, whereby in the f0 forward state was 0.16 meters , but in the SDL forward state the horizontal force only increased with a deflection of 0.05 meters. However, the overall result is that the stress states that occur are still below the limit or permissible conditions, based on the stress-strain curve of the cable material, the stress under operating conditions is still in the elastic range of the material.

Abstract

This study evaluates the condition of 215 bridges across 18 sub-districts in East Kutai Regency using a Bridge Management System (BMS). Primary data was collected through visual inspections, analyzing element-specific (foundation, substructure, superstructure, and deck) and overall condition ratings. The bridge inventory is predominantly timber construction (48.37%) and features mostly short spans, though critical long-span bridges exist. Results indicate most foundation, substructure, superstructure, and deck elements are in good condition (ratings 1-2). However, a significant percentage of elements show moderate to severe damage (ratings 3-5), with 1.86% of decks and superstructures in critical condition. A bridge prioritization model was developed based on condition ratings and urgency. Strategic recommendations include data-driven maintenance planning, efficient budget allocation, and enhancing human resource capacity and technology for sustainable bridge asset management, minimizing infrastructure failure risks

Abstract

The Sei Busui Batuaji-Kuaro Bridge in East Kalimantan, Indonesia, is a critical infrastructure project requiring rigorous hydrological analysis to ensure resilience against extreme flood events. This study presents a comprehensive hydrological simulation to determine design flood discharges and maximum water levels (MWL) using rainfall data from 2016–2025. Rainfall frequency analysis employed the Log Pearson Type III distribution, validated with Chi-square and Smirnov-Kolmogorov tests. Flood discharges were estimated using five methods: Rational, Weduwen, Haspers, HSS-Gamma I, and HSS-Nakayasu. The HSS-Gamma I method was selected for its applicability to medium-sized catchments (127.58 km²), yielding a design discharge of 1,623.15 m³/s for a 75-year return period. Hydraulic analysis confirmed a freeboard of 1.693 m, exceeding safety standards. The findings emphasize the importance of region-specific hydrological methods and continuous monitoring to mitigate flood risks

Abstract

Box culverts are critical infrastructural elements routinely subjected to complex soil-structure interaction phenomena. The conventional approach of assuming rigid foundation supports often leads to an unrealistic distribution of internal forces, potentially resulting in overly conservative or dangerously unconservative designs. This study investigates the structural behavior of a reinforced concrete box culvert by comparing a fully rigid support model against subgrade reaction models utilizing spring placements. Specifically, the analysis evaluates the variations in maximum bending moment (Mmax), axial force (Pmax), maximum shear force (Vmax), and deflection (Δ) across the top slab, vertical walls, and bottom slab. The spring models are further dissected into three configurations: springs without rigid links, springs with 4 rigid links, and springs with 8 rigid links. The findings reveal that the transition from rigid to spring supports fundamentally alters the load distribution, significantly reducing bottom slab axial forces from 135.94 kN to 0.00 kN in extreme cases, while modifying shear and moment profiles across the structure. The inclusion of rigid links demonstrates a stabilizing effect, closely mimicking realistic soil restraint while preventing localized stress concentrations. This research provides critical insights for engineers seeking to optimize box culvert designs by accurately modeling subgrade reaction.
