Abstract:The structural behavior of reinforced concrete framed shear walls subjected to reversed cyclic lateral loading were studied by testing ten large-scale specimens, including high-, middle-, and low-rise shear walls. An analytical model was also proposed to predict the behavior of the tested specimens. The parameters of concrete strength and vertical stell ratio of walls were investigated. The predicted maximum load and corresponding displacement, and load-displacement curves satisfactorily agreed with the experimental results. In addition, the experimental results showed that the failure mode of high-rise shear walls was flexural; their ductility factors were greater than those of low-rise shear walls; their displacements were also greater. The mid-rise shear walls failed by a combination of both flexure and shear. The experimental results also showed that the maximum loads were greater for specimens with higher concrete strength or higher verical stell ratio. The vertical stell ratio of walls has more significant effect on flexure-predominant walls. However, it is insensitive to shear-critical walls. It was found that the simple model develped from previous small-scale tests could not closely reflect the experimental results of all specimens. This suggests that the size effect needs to be taken into account in the analytical model.
