However, many practicing engineers still assumes that the walls are non-structural walls due to complexity of evaluating the failure modes of masonry infill and its interaction with the surrounding frame. A practical and simpler seismic evaluation method is needed to assess masonry infill walls. The Japanese seismic evaluation method is a practical seismic evaluation method. However, procedure to calculate the masonry walls strength and ductility are not mentioned in the standard because masonry walls are not a common practice in Japan. First, past experimental data and in-plane strength estimation methods are reviewed and compared. A simpler equation with quite good accuracy based on experimental data is proposed to calculated the in-plane shear capacity. Then, reduction factor of lateral strength due to openings proposed by different researchers is compared with experimental data to check their applicability. Deformation capacity and ductility of RC frames with masonry infill is studied based on experimental data. It was found that the deformation capacity is of a wide range and influencing parameters need further research. Finally, recommendations on how to address the influence of masonry infill into the Japanese seismic evaluation are proposed.
