Correlation between Static and Dynamic Response of Model Masonry Structures

Abstract

The paper presents correlations between response of the same structural system subjected to either dynamic shaking or static lateral forces. Two one-quarter scale test structures were constructed with identical designs and were tested in the laboratory using two different methods. The first structure was subjected to simulated earthquake motions on a shaking table while the second structure was forced to displace through the same history at static rates using computer controlled servohydraulic actuators. Characteristics of dynamic lateral force distributions are examined first and followed by a description of techniques used for the static loading experiment. Correlations are made between observed response of the statically and dynamically tested twin structures to suggest differences in strength, stiffness and energy dissipation that may arise with each test method.
