Shear behavior of a new composite shear wall system is investigated through a series of cyclic loading tests on a total of four specimens. One specimen was designed such that shear failure would occur in the CFT columns connecting RC wall panels to the grade beam. The failure caused large axial shortening of the specimen. Small section wide flanges were used as the rims of the RC wall panels of two specimens were small. Failure was mainly instigated after these wide flanges yielded, because of large deformation of the wide flanges that led crashing of RC panel. Hysteresis of these three specimens was relatively stable, unlike those observed fbr RC shear walls in general. FEM was employed to simulate elastic-plastic behavior of the specimens. Design methods to prevent shear failure of CFT and RC panels are suggested using the analytical and test results.
