Earthquake Resistant Structural Walls, Tests of Isolated Walls. Phase II

摘要

Behavior of structural walls for use in earthquake resistant buildings is studied. Included is a presentation of results from sixteen tests on isolated walls. The tests were conducted in an attempt to develop design criteria for reinforced concrete structural walls in earthquake resistant buildings. The objective is to determine ductility, energy dissipation capacity, and strength of a wide variety of walls. Isolated walls representing those found in structural wall systems were tested. Controlled variables included shape of the wall cross-section, amount of main flexural reinforcement, amount of hoop reinforcement around the main flexural reinforcement, amount of horizontal shear reinforcement, axial compressive load, concrete strength, and load history. Two walls were repaired and retested. Observations based on test results are given.
