Abstract

Trusses have long been integral to structural design due to their efficiency in bearing loads. However, lacking clear guidelines for optimizing truss beams often forces engineers to compromise performance and cost. This study addresses this gap by optimizing the shape and size of two-dimensional steel truss beams using Finite Element Analysis with ABAQUS software under specified conditions. The analysis considered uniform vertical loads of 200 kN, 500 kN, and 200 kN applied at strategic joints, with pinned supports as boundary conditions. Four truss configurations, V-structure, V-structure with vertical members, Nstructure, and K-structure, were examined for stress, displacement, and critical buckling. Least deflection (-12.28 mm) and maximum stress (178.85 MPa) were found for the K-structure, suggesting a suitable design. Additionally, the High Edge A (HEA) 240 steel cross-section was determined to be the ideal alternative from a range perspective, yielding a construction with enhanced stability and financial aspects. This work shows how to have a much betterperforming truss with the largest saving potential and the least material. The result is expected to have significant implications for the design of safer and more economical steel trusses, which are important components of many modern buildings.
