Concrete-Filled Composite Plate Shear Walls (CF-CPSW) consist of pre-fabricated steel modules filled with plain concrete. During construction, the empty steel modules are designed to support multiple floors of the steel framing before the concrete is infilled, and they act as permanent formwork. CF-CPSW systems can lead to improved constructability and reduced construction schedules. In coupled CF-CPSW lateral force resisting systems, the coupled walls resist global over turning moment through an axial force couple and individual wall flexural resistance. Therefore, in order to design the coupled CF-CPSW system, the wall’s flexural behavior under axial load must be evaluated. This study reports the results of an experimental investigation of the contributions of axial loading, tie reinforcement ratio, and plate slenderness ratio on the cyclic flexural behavior of planar rectangular CF-CPSWs with flange plate boundary elements under compressive axial load. The lateral force-displacement behavior, plastic rotation capacity, and moment-curvature response of three wall specimens were experimentally evaluated in this thesis. A fiber analysis model for calculating the section moment-curvature behavior of the planar walls was developed and validated using the experimental results. An increase in axial load level resulted in an increase in flexural capacity of the wall. All three wall specimens showed high ductility in their experimental moment-curvature responses and a minimum plastic rotation capacity of 0.0141 radians. The peak point of the fiber analysis moment-curvature curve occurs after the compression strain in the steel exceeds 2εy.
