Many of the buildings which experienced damage in the recent earthquakes such as 2015 Nepal Earthquake, were RC buildings having partitions of masonry walls. This study proposes a simplified procedure to estimate the in-plane seismic capacity of masonry infilled RC buildings based on concepts of the Japanese seismic evaluation standard. The seismic capacity and observed damage correlation for a database of 370 of existing RC buildings with masonry infill that experienced earthquake in Taiwan, Ecuador and Nepal is investigated and recommendations for seismic criteria are discussed.
