Flexural Behaviour of Built-Up Beams Made of Optimised Sections

The modular construction industry often seeks cost-effective, high-performing, and longer-span members in buildings to ensure efficiency quality. Accordingly, the idea of built-up sections was brought into gain numerous benefits including higher structural capacity, improved torsional rigidity, increased stiffness. While limited research studies have been carried out study performances sections, few innovative section profiles developed considering benefits, Hence, application newly could enhance employment industry. On that note, this is focused on flexural behaviour optimised named LCB-benchmark (Lipped Channel Beam), optimised-LCB, folded-flange super-sigma sections. In addition, different materials, namely cold-formed carbon steel (CFS), (CF) aluminium CF stainless steel, were considered for order provide recommendations based their performances. Numerical analysis single as well parametric plan after successful validation experimental studies. results compared Finally, comparisons, recommended all three materials it displayed highest bending capacity enhancement corresponding a minimum 131%.
