SHEAR STRENGTH OF LOW-RISE WALLS WITH BOUNDARY ELEMENTS

Results of tests on eight specimens representing low-rise shear walls with boundary elements are reported and analyzed. The principal variables included amount of flexural reinforcement, amount of horizontal wall reinformcement, amount of vertical wall reinforcement, and height-to-horizontal-length ratio. Flexural reinforcement was varied from 1.8% to 6.4% of the boundary element area; horizontal wall reinforcement and vertical wall reinforcement were varied from 0% to 0.5% of the wall area; and height-to-horizontal-lenght ratio was varied from 1:4 to 1:1. The test program was designed to determine the effect of load reversals. One specimen was repaired and retested. Results indicate that current design procedures underestimate the strength of lowrise shear walls, even when the walls are subjected to reversed load. A suggested design procedure is presented.
