Based on equilibrium and compatibility conditions, as well as a softening stress-strain relationship for concrete, a truss model theory was presented to predict the behavior of low-rise structural walls under static loads. In this paper, shake table tests on low-rise structural walls are performed, so that the previously proposed truss model theory can be examined by the test results, and the effect of acceleration frequency on such walls is studied. It is found that both the experimental ductility and dissipated energy decrease with increasing acceleration frequency, and when such walls are subjected to dynamic forces, the static truss model theory can be used for the prediction of the shear strength, but not for the prediction of the displacement at the maximum shear force.[PUBLICATION ABSTRACT]
