Without considering the intensity limit of delamination damage of the two materials, an integrated stiffness matrix is formed with the combination of stiffness matrix of steel-wall shell element and that of concrete spatial block element.
Introduction Since the thin-walled steel-concrete composite structure consists of steel and concrete, two materials different in nature, the mechanical property obviously depends on their respective characteristics.
