STRUCTURAL BEHAVIOR OF REINFORCED-CONCRETE FRAME WALL COMPONENTS

Reinforced concrete buildings with shearwalls are very efficient to re sist earthquake disturbances. In general, reinforced concrete frames a re governed by flexure and shearwalls are governed by shear. If a stru cture 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 compressive streng th, section size and wall on the frames are investigated. For frames, the horizontal force-displacement relationship predicted by the trilin ear 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-displace ment relationship.
