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.

Prince Suryanata Street is a connecting road between the North Samarinda District of Samarinda City and the Tenggarong District of Kutai Kartanegara Regency. Frequent congestion of all types of vehicles, both entering and exiting the center of Samarinda City, causes traffic jams on this road segment. Additionally, the high population density in the area around Prince Suryanata Street also contributes to the heavy traffic. The traffic problems on Prince Suryanata Street in Samarinda City are now being felt by road users. One issue that further worsens the traffic conditions is the poor performance of the road segments. Therefore, an evaluation of the road is necessary. The traffic flow volumes are as follows: Monday, 9834.75 pcu/hour; Friday, 5911.95 pcu/hour; and Saturday, 5690.8 pcu/hour. The highest traffic volume occurs on Monday due to various school activities and community activities around the observation location. The analysis results show that Prince Suryanata Street experiences high traffic density, especially during peak hours, leading to a decline in road service quality. The current capacity (C) is 244.76 pcu/hour, the degree of saturation (ds) is 1.68, and the Level of Service (LoS) is rated at class F. For the 10-year forecasting, the projected capacity (C) is 6397.44 pcu/hour, the degree of saturation (ds) is 0.95, and the Level of Service (LoS) is anticipated to be in class D.
