Sustainable Practices on Metallic Foam Sandwich Panels in Steel Plate Shear Walls as a Part of Green Building
摘要
Steel plate shear walls (SPSW) consist of steel infill plate connected to the boundary elements. It possesses high initial stiffness, ductility, redundancy, and energy absorption capacity. These enable SPSWs to be a preferred choice for lateral load resisting systems in high wind and seismic regions. Metallic foam sandwich panel (MFSP) consist of thin metal sheets attached to a lightweight core which would exhibit high stiffness, ductility, and energy absorption capacity. This study investigates the potential of using MFSP in place of conventional steel plates in the SPSW system using finite element software Abaqus. The investigation on MFSP in SPSW is a step towards innovative, sustainable, and resilient structural systems. It addresses contemporary challenges in construction, lightweight materials, seismic resistance, and energy efficiency while aligning with global goals of sustainability and structural optimization. MFSP are recyclable and produced with eco-friendly methods, aligning with green building principles. They enhance energy efficiency and reduce carbon footprints in SPSWs which support sustainable construction practices. Numerical modelling of SPSW was performed using both conventional steel plates and MFSP. Non-linear pushover analysis was performed with a specified target displacement. Also, non-linear dynamic analysis with cyclic loading was performed to evaluate ductile behaviour. The analysis results demonstrated that MFSP-SPSWs possess high stiffness, ductility, redundancy, and energy absorption capacity which enable them excellent substitute for conventional SPSWs. It was concluded that ultimate strength and energy dissipation capacity of MFSP-SPSW has increased approximately by 20% as compared to conventional SPSW.
