Abstract

This activity is a community service carried out by UMKT Civil Engineering students who are integrated with UMKT Civil Engineering Lecturers for two months. The collaboration carried out by students with industry partners in the weighing-bridge construction project showed an essential contribution to the integration of actual and theory. The focus of this community service activity is the implementation of work methods on bored pile foundation work. Student activities include direct observation, interviews, and comparative theory analysis with field practice. The activity results focus on Standard Penetration Test (SPT) soil testing data, determining weighing-bridge bored pile points, and implementation methods. Through this activity, students and lecturers play an active role in providing accurate contributions to industrial partners in ensuring the efficiency and quality of the implementation of bored pile foundations. Thus, this activity not only provides solutions to problems faced by industrial partners but also serves as a direct learning medium for students. This emphasizes the importance of an interdisciplinary approach that combines science, technology, practical expertise, and academic theory in planning bored pile foundations for weighbridges.

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.
