This report presents the experimental results obtained in the third phase of an ongoing investigation on the seismic behavior of reinforced concrete walls. The ultimate objectives of this investigation are to find ways of designing and constructing R/C walls with large energy absorption and dissipation capacities under the effects of severe seismic excitations and to develop practical methods for the seismic design of combined wall-frame structural systems. Although the main objective of the studies reported here was to investigate the effects of the amount and arrangement of wall-panel reinforcement on the overall seismic performance of the walls, additional objectives were to study (1) the effectiveness of the epoxy-injection technique for repairing damaged walls, (2) methods for strengthening walls after their local failure, and (3) the effects of construction joints. Two one-third scale models of the three bottom stories of the wall of a ten-story frame-wall R/C building, designed according to UBC/73 seismic code requirements, were constructed and studied experimentally.
