The multi-ribbed composite wall (MRCW) structure has the advantage of energy-saving, low weight, and adjustable stiffness. The partition, enclosure, and load-bearing capacity can be realized simultaneously. When the steel frame embedded and hung with the intercalated multi-ribbed composite wall (MRCW), the steel frame columns are avoided to expose in the air, so the durability and heat insulation performance of the structure can be improved. The steel frame is connected with the intercalated multi-ribbed composite wall (MRCW) by wet connection, and the mechanical property and the deformation mode of the multi-ribbed composite wall (MRCW) and steel frame are researched. The mechanical property of stud shear connectors is qualitatively and quantitatively analyzed, which is beneficial to improve the related design methods of structures.
