Buckling Behavior of Steel Plate in Composite Shear Walls with Double-Skin Steel Plate and Filled Concrete Under Compression
摘要
Abstract
Since the double-skin steel plate concrete composite wall can be used as the lateral force resisting member,there are some advantages,such as high capacity,excellent energy dissipation and favorable ductility.Double-skin steel plate concrete composite walls in high-rise buildings are subjected to vertical loading,but the elastic buckling of steel plate is not allowed.Although the initial geometrical imperfection of steel plate is a critical influencing factor for the buckling stress,it was not considered in the calculation of the buckling stress.The finite element model(FEM)of double-skin composite walls was established by using ABAQUS in consideration of initial geometric imperfection of steel plate.The buckling strain of steel plate,load-displacement curves and failure modes obtained by FEM matched well with those from the test.The parametric analysis was conducted to study the influence of initial geometric imperfection,welding spot spacing-to-thickness ratio and steel yielding stress.The equation of steel plate buckling stress accounting for initial geometric imperfections was proposed.关键词
