Progress of unilateral contact buckling of steel skin sheet in composite wall

Steel-concrete composite wall is a novel composite structure composed of thin sheet steel outer skin filled with light weight concrete. The composite wall panel can be used as bearing member and also as maintenance structural plate, which can satisfy functional requirement of building including bearing capacity, heat insulation and preservation. As a concerned matter in engineering field, investigation progress of unilateral contact buckling of steel skin sheet is presented by summary, analysis and contrast of relevant results.
