This study investigates the influences of shear-mode mullion-type walls on the performance of RC rigid-frames. To express shear-axial coupled motion occurred with shear imlure of walls, shear-axial softening behavior was modeled using the theory of plasticity and the concept of failure surface contraction. Pushover analysis was then conducted to RC frames that have various combinations of column over-design factors and wall breadths to simulate response to the seismic load and collapse mechanism. Some frames with low column over-design factor showed partial collapse after shear failure of walls, while others showed more ductile mechanism. The results revealed how shear-mode mullion-type walls can affect the performance of RC frames with different configurations.
