Experimental Research on Seismic Behavior of I-Section Composite Shear Wall with Steel Plate Reinforced Concrete

Article Preview

Abstract:

In order to study the seismic performance of low shear-span ratio composite shear wall with steel plate reinforced concrete,three low shear-span ratio composite shear walls with steel plate reinforced concrete were tested.The deformation performance and failure modes were observed under low cyclic lateral loads with high axial compression ratio.Valuable results were obtained for the hysteretic curves,skeleton curves,ductility and energy dissipation capacity.The results indicate that the elastic stage, Specimen stiffness value is larger, and the stiffness change is basically the same; The specimen into the elastic-plastic stage, cracks have appeared in basic beam and early damage. The junction of steel concrete structure and reinforced concrete structure are prone to failure, which should improve the reinforced concrete shear stiffness in the design.
