Analisis Statik Variasi Beban Terhadap Respons Struktural Pada Bridge Linetrack Menggunakan Metode Elemen Hingga

Abstrak

Static analysis of the Bridge Linetrack is essential to ensure structural safety under human loading during operation. This study specifically aims to analyze the influence of static load variations on the stress distribution, deformation response, and safety factor of the S45C steel Bridge Linetrack using the Finite Element Method (FEM). Three load variations were applied 539.55 N, 686.7 N, and 873.09 N representing light, medium, and heavy human weight categories. The simulation results indicate that increasing the applied load leads to a rise in Von Mises stress from 40.812 MPa to 66.041 MPa and an increase in displacement from 0.943 mm to 1.525 mm, accompanied by a reduction in the safety factor from 7.473 to 4.618. All stress values remain significantly below the yield strength of S45C steel (305 MPa), confirming that the structure stays within the elastic range and is safe from plastic failure. This study demonstrates that the Bridge Linetrack possesses adequate stiffness and structural strength to withstand variations in human load and can serve as a reference for developing more efficient and safer bridge designs.
