EXPERIMENTAL STUDIES ON LOW-RISE STRUCTURAL WALLS

Based on equilibrium and compatibility conditions, as well as a soften ing stress-strain relationship for concrete, a truss model theory was presented to predict the behavior of low-rise structural walls under s tatic loads. In this paper, shake table tests on low-rise structural w alls are performed, so that the previously proposed truss model theory can be examined by the test results, and the effect of acceleration f requency on such walls is studied. It is found that both the experimen tal ductility and dissipated energy decrease with increasing accelerat ion frequency, and when such walls are subjected to dynamic forces, th e static truss model theory call be used for the prediction of the she ar strength, but not for the prediction of the displacement at the max imum shear force.
