A Comparative Investigation of the Flexural Performance in Various Steel Truss Bridge Configurations

This article presents a comprehensive comparative investigation focused on the flexural performance of various steel truss bridge configurations. The study aims to assess and analyze the structural behavior of different bridge designs under diverse loading scenarios and geometric arrangements. Through a combination of experimental testing and analytical assessments, the research provides critical insights into the load-carrying capacity, response to external forces, and overall flexural behavior of these configurations. The results shed light on the relative strengths and weaknesses of each design, offering valuable guidance for decision-makers in the field of bridge construction and infrastructure development. This comparative investigation contributes to the advancement of engineering knowledge. It aids in the selection of optimal steel truss bridge configurations for specific applications, ultimately enhancing the safety and reliability of such vital structures. The study uses the SAP2000 program with the loading used according to the regulations of SNI 1725: 2016. The results of the analysis show that the largest deflection occurs in the modeling of steel truss bridges with the Howe truss type, with a deflection value of 67 mm, while the smallest deflection occurs in the modeling of steel truss bridges with the Warren type, with a deflection value of 63 mm. The higher the self-weight of a steel truss, the smaller the deflection it produces. As evident in the graph of the Warren truss type, which has the highest self-weight, it also exhibits the smallest deflection.
