The in-plane seismic performance of framed masonry wall has been studied by many researchers all over the world, whereas structures subject not only in-plane load but also outof-plane load simultaneously in actual events. This paper utilizes three dimensional nonlinear finite element analysis techniques to investigate the effect of out-of-plane load on the inplane seismic behavior of reinforced concrete (RC) framed masonry wall. The analytical results indicate that the pre-applied out-of-plane

When the out-of-plane load is small enough, masonry wall fails in terms of in-plane strut mode. With the increase of the out-of-plane load, failure mode under in-plane load tends to become arching failure mode.
