Traditional brick walls face notable limitations, particularly in their weight and vulnerability to lateral forces, which can lead to significant damage under seismic conditions. This study investigates Cold-Formed Steel (CFS) and plywood composite walls as an alternative solution, focusing on lateral load performance. Laboratory tests on CFS-plywood wall specimens, both with bracing and without bracing, allowed for a comparison of lateral load capacity, deflection, and crack development. The findings reveal that bracing improves lateral stability significantly, enabling the braced walls to support a peak load of 14.127 kN compared to 13.77 kN in unbraced walls. Additionally, bracing reduces deflection and distributes cracks more evenly, presenting CFS-plywood composite walls as a lightweight, resilient choice for earthquake-resistant structures.
