Research on the Axial Compressive Performance of the Concrete-Filled Steel Shear Wall with Binding Bars

Abstract:

The concrete-filled steel shear wall with binding bars is a new kind of lateral force resisting structure, which assembles binding bars with certain spacing. The behaviors of the structure under axial compression, containing bearing capacity and ductility, are studied by the software ABAQUS. Some factors as length-width ratio, bar spacing, steel thickness and material's strength grade, are taken into account. The results show that the axial compressive bearing capacity factor λ increases with length-width ratio b/t increasing; the factor λ, the ductility factor DI and the vertical displacement decrease with bar spacing d increasing; the bearing capacity factor of steel plate λ_s and DI increase while the factor λ decreases with steel thickness t_s increasing; and with the concrete's strength grade and steel's strength grade improving respectively, both the factor λ and DI decrease. At the same time, the structures simplified formula under axial compression is presented.
