However, there were few adequate studies on the seismic behavior of these members. Additionally, it has been pointed out that beams with low shear margin have possibility to cause shear failure. In this research, static loading tests were conducted to investigate seismic behavior of beams with non-structural walls having structural gap. Six beams with different parameters were investigated as the following. Two beams: a beam with shear margin of near 1.1, one beam: spacing between stirrups in hinge regions was decreased, three beams: with slab and their walls are as spandrel or hanging wall. The experimental results were as the followings. For two beams with wall simply, after yielding of main bars, shear failure with fracturing of stirrups occurred. For four beams, spacing between stirrups was decreased and with slabs, were able to finish the tests without shear failure. As the test results, the beam with non-structural wall having structural gaps had the possibility of shear failure occurred, even in the beam having more than 1.1 of shear margin. Moreover, it was found that it was possible to prevent shear failure by increasing the end reinforcement and effect of the slab restraint.
