Structural behavior of reinforced concrete frame-wall components

Reinforced concrete building with shearwalls are very efficient to resist earthquake disturbances. In general, reinforced concrete frames are governed by flexure and shearwalls are governed by shear. If a structure includes both frames and shearwalls, the complicated interaction of these two components will exist. This paper describes experiments on frames and frame-wall structures, and the experimental results are used to check the analytical models. The tests include four frames and two frame-wall structures. The effects of concrete com-pressive strength, section size and wall on the frames are investigated. For frames, the horizontal force-displacement relationship predicted by the trilinear theory is in good agreement with the test data. However, for frame-wall structures, both the softening truss model and the IDARC program give deviations from the test values in the horizontal force-displacement relationship.
