Abstract:
Results of an experimental investigation to determine inelastic load-deformation character istics of reinforced concrete structural walls are reported. Sixteen large structural walls have been tested. These tests show that structural walls possess signif icant rotational ductility when subjected to reversing loads. In addition, it was found that shear distortions within the hinging region of a wall are coupled to flexural rotations. Therefore, inelastic shear distortions should be considered in structures designed to utilize the inelastic capacity of struc-tural walls for earthquake resistant construction.
