This retrofit project involves structurally upgrading an existing barn by reducing the interior support system from three columns to two. The current non-compliant beam will be removed and replaced with a new steel beam designed to meet current code requirements. Reinforcement includes the installation of steel HSS (Hollow Structural Section) columns to provide increased load capacity and stability. The retrofit enhances open interior space while ensuring structural integrity and long-term durability. This upgrade not only modernizes the structural system but also improves functionality for future adaptive reuse-- whether for agricultural storage, processing or recreational purposes
