ABSTRACT
The optimisation in this study is shown on a sway frame structure made of welded I-section members. Structural stress, stability constraints, frame strength, and load-bearing capacities were all considered. The load-bearing capacity of the structure was maximised—using a FEM (Final Element Method) AXIS package for the simulation. Further we carried out test calculations using MathCAD, where our results examined stresses on a welded beam-to-column connection. It was found that significant material could be saved this way. Further development to extend calculations will be using different steel grades and different semi-rigid beam-to-column connections.
