Abstract:The results of an experimental investigation to determine strength of rectangular low-rise structural walls for buildings are presented in this report. Seven large specimens with "height-to-hori-zontal- length" ratios of 1.0 were subjected to static in-plane horizontal loads. One of the specimens was subjected to ten cycles of load reversals. Variables in the test program were amount and distribution ofvertical and horizontal reinforcement. The walls did not have any boundary elements or special hoop reinforcement. No vertical load was applied. Results indicate that low-rise rectangular walls can develop shear stresses on the order of 10 f'c psi (0.83 f'c MPa). Also, results indicate that shear strengths implied by Section 11.10, Special Provisions for Walls, of the 1977 ACI Building Code provide a reasonable lower bound capacity, even when load reversals are applied.
