An extensive investigation is conducted on experimental data to improve modification factors of masonry infills. For this, available experimental data are classified based on the frame and infill materials. Then a sensitivity analysis is carried out for the effective parameters on the m-factor, including relative stiffness of infill to the frame, the material of infill or frame, aspect ratio, etc. To calculate m-factors of specimens, both the backbone and the envelope curves of the hysteresis curves, proposed in ASCE41-06 and ASCE41-13, respectively, are applied. The obtained results confirmASCE41-13 for giving more conservative m-factor values. Sensitivity analysis shows that infill m-factors highly depend on the infill and frame materials, rather than the infill aspect ratio and relative stiffness of the frame to the infill. Finally, some values are proposed for m-factors of infill panels, made of clay brick or clay tile, surrounded by steel or concrete frames.
