Abstract

Steel plates in double skin composite (DSC) panels may buckle locally between shear connectors when subjected to biaxial compression. The local and post-local buckling behaviour of biaxially compressed steel plates restrained by discrete stud shear connectors in DSC panels is studied in this paper by using the finite element method. The shear stiffness effect of stud shear connectors is considered in the determination of elastic local buckling coefficients. The post-local buckling strength of steel plates in biaxial compression is investigated by performing a geometric and material nonlinear analysis. The initial imperfections, material stress-strain relationship and shear-slip behaviour of stud shear connectors are taken into account in the post-local buckling analysis. Biaxial strength interaction curves and design formulas are developed for the design of steel plates in DSC panels under biaxial compression.
