Abstract

Weighbridges play a vital role in coal mining operations. This study aims to calculate the stress range and fatigue life of steel bridge girder cross-sections. Using the numerical simulation method with the CSI Bridge v22 application, the maximum axial force of 197 kN and the minimum axial force of -74 kN were obtained. The axial force is determined from the first 3 spans of the bridge with a span length of 4 m. The span length of the weighbridge is 80 m. From the calculation, the maximum stress of 40.11 MPa and the minimum stress of -15.06 MPa were obtained, resulting in a stress range of 55.16 MPa. The nominal bending moment strength of the beam was found to be 0.56. This modeling allows the simulation of dynamic loads from a 400-tonne SDT truck (semi-trailer door tipper) passing over the bridge so that accurate stress range data can be obtained. Fatigue analysis was carried out using the Basquin equation using the constant C = 1x1012 and exponent m = 3, receiving a fatigue life of 0.006 (6.01x106) cycles assuming 30-40 hauling trucks passing over the weighbridge. The results of calculations and simulations obtained longitudinal and transverse profile dimensions of IWF 1000x520x18x31.

Abstract

Bridge reinforcement with external prestressing method is a proven effective approach to overcome damage in strengthening bridge structures. This method uses the installation of prestressing cables outside the steel frame of the bridge to increase the strength and stability of the structure. The bridge structure is made with the guidelines of SNI 1725: 2016 standard steel frame of class A bridges, using IWF and H Beam steel, with a plate thickness of 20 mm with a span length of 60 meters, a width of 9.13 meters and a height of 6.3 meters. The structural analysis of this study uses the SAP2000 v22 software program. In this study, 3 prestressing cable tensions were compared on the reinforcement of the bridge frame with the external prestressing method. And a loading simulation was carried out which could provide a response in the form of strain due to moving loads and a bridge structure response that was reduced by approximately 50% from the deflection force on the steel frame reference bridge if given a moving load. Choosing a bridge that has the lowest settlement. The review point is determined for the comparison of deflection at point object 7 and joint object U3. The Type E cable-stayed bridge has the lowest results in percentage, about 46.68% for a speed of 40 km/h, 48.60% for a vehicle speed of 50 km/h and 49.91% for a vehicle speed of 60 km/h, indicating that this bridge has the best analysis performance among the cable-stayed bridges analyzed.

Abstract

Penelitian ini menganalisis kinerja lalu lintas pada ruas Jalan Ir. H. Juanda dan memberikan rekomendasi jika kinerja tidak memenuhi standar PKJI 2023. Penelitian ini dilakukan pada Jalan Ir. H. Juanda karena kinerja ruas jalan tersebut seringkali padat maka digunakan software PTV VISSIM untuk mensimulasikan kondisi terkini 2025 dan 10 tahun mendatang 2035. Dilakukan survei lalu lintas selama 3 hari di jam 07.00-08.00 WITA, 12.00-13.00 WITA, dan 17.00-18.00 WITA, dengan interval waktu 15 menit selama satu jam pada hari senin, jumat, dan sabtu. Data yang dikumpulkan berupa jumlah kendaraan dengan satuan kend/jam dan data geometrik dengan posisi surveyor masing – masing 1 orang pada jalur kanan dan kiri, panjang pengamatan yaitu 200 meter. Survei lalu lintas pada 26 Februari 2025 menunjukkan jumlah kendaraan puncak 4940.8 smp/jam dengan kapasitas jalan 6392 smp/jam dan tingkat kejenuhan 0.77, yang menunjukkan tingkat pelayanan C. Proyeksi 10 tahun mendatang menunjukkan penurunan tingkat pelayanan ke F dengan tingkat kejenuhan 1.18 jika kapasitas jalan tidak ditingkatkan. Rekomendasi meliputi mengubah tipe jalan, menambah lebar jalan, dan mengurangi lebar bahu jalan, yang diharapkan meningkatkan kapasitas menjadi 9211.31 smp/jam dengan tingkat kejenuhan 0.79 (tingkat pelayanan D), sehingga dapat menangani permintaan pergerakan lalu lintas 10 tahun mendatang dan menjaga tingkat pelayanan.

Abstract

Expansion joints of the strip seal type are essential structural components in modular steel truss bridges, functioning to accommodate movements caused by thermal expansion, structural deformation, and repeated traffic loading. Over time, these components are significantly affected by cumulative material degradation mechanisms, making fatigue evaluation necessary to ensure their reliability. This study presents a comprehensive assessment of the fatigue performance of strip seal joints by implementing the Constant Amplitude Load Factor (CALF) approach, a correction factor that converts variable traffic load spectra into equivalent constant-amplitude cyclic loading. The research methodology includes mapping traffic loads into Equivalent Single Axle Load (ESAL) units and axle load spectra, calculating CALF values based on the Palmgren–Miner cumulative damage theory, and applying S–N (stress–life) curves for steel and elastomer materials, each having different fatigue exponents. In addition, a damage contribution distribution analysis for each load class is conducted to determine the component’s sensitivity to variations in heavy traffic intensity. The results indicate that strip seal expansion joints exhibit satisfactory fatigue resistance under normal traffic loading conditions; however, an increased proportion of heavy axles significantly accelerates damage accumulation and shortens the designed service life. Therefore, this study emphasizes the importance of considering actual load spectra through the application of the CALF concept during the planning stage, supported by quality control in installation details and construction procedures to prevent potential failures in strip seal expansion joints
