To reach this goal 4 half-scale single-story single-bay masonry infill specimens were tested. Two specimens had moment-resisting steel frames, while the remaining specimens had simple steel frames. For each type of frame, one subjected to combined lateral and vertical loading and another applied under only lateral loading. Comparing the results of experimental test showed that the vertical load had not significant influence on the in-plane stiffness and strength of the infill specimens. Regarding the using of infill panels for retrofitting and strengthening of the existing building, the seismic guidelines have recommended linear and nonlinear procedures to estimate stiffness and strength of infills. The parameters for linear procedure include m-factor and expected capacity. These parameters were calculated based on experimental results through idealized backbone curves. The results show that the parameters of linear procedure do not affect by vertical load in the specimen with moment-resisting frame. However, the m-factor is considerably increased in the infilled simple frame specimen by applying vertical load. Finally, it can be concluded that the vertical load is beneficial for the in-plane behavior of infilled frame especially in the infill surrounded by simple frames. Therefore it is recommended that the effect of vertical load as well as connection rigidity of frame should be considered in seismic guidelines for infilled frames.
