In order to study the seismic performance of high-strength concrete composite shear walls with embedded steel strips, four tests for high-strength concrete composite shear walls with embedded steel strips (SPRCW-1 to SPRCW-4) were constructed and tested. For ribs parallel to the beam the design resistance is determined in accordance with clause 6. A major difference between the shear stud behavior in the proposed system and in composite beams is that in the proposed system, the amount of concrete available to resist punching shear is limited due to the small depth of the flat. Positioning. D. Shear Connector Studs are designed to tie the concrete to the steel beams and to resist shear loadings between the concrete slab and steel beam in composite construction.
