- Abstract
- An experimental program is presented to develop design criteria for reinforced concrete walls used as lateral bracing in earthquake resistant buildings. The primary concern is the ductility, energy dissipation, and strength of the walls. The program is divided into three parts--reversing loads applied to isolated walls, reversing loads applied to wall-systems, and testing of elements of systems. Each is discussed in detail, including descriptions of test specimens, apparatus and results, as well as interim conclusions and recommendations. Isolated walls represent an element of a structural wall system, and are being tested to determine their strength, ductility, and energy dissipation capacity. The ability of structural wall systems to resist lateral loads is being investigated to evaluate structural details necessary to assure intended interaction between the walls and the rest of the structure. Tests are being performed on specimens representing the compression zones of structural walls to evaluate the effect of confinement reinforcement and to determine the effective stress-strain curve of confined concrete.
