Abstract: This paper presents the results of an experimental study on the behavior of a new-type cold-formed steel composite wall panel subjected to monotonically increasing in-plane shear deformation. The framework is composed by columns, upper beam and bottom beam and filled with composite wooden panels. For its lack of study on mechanical properties, by comparing with the traditional composite wall, the deformation, damage form, load-shear displacement relation, stress of the columns and strain of the panels are discussed in order to verify its rigidity and shear capacity in order to provide suggestion for structural optimization.
Keywords: shear wall panel; cold-formed steel; composite wooden panel; monotonic loading; shear capacity
