Mixed and composite structures Study on the shear strength of composite concrete and steel plate shear walls with binding bars

Through-thickness steel bars (binding bars) are used to connect the long-side steel plates. These bars enable composite action of the plates and concrete and serve to limit steel plate buckling. In addition, concrete confined by the steel plates is in multi-axial compression and its shear capacity is significantly improved (Emori K. 1989). The objective of this study is to obtain a method to clearly model the composite action and to calculate the shear strength of S/C walls on the basis of multi-axial concrete strength theory.
