| 要旨 |
In developing countries, there are enormous stocks of vulnerable masonry infilled RC buildings, which are required to be identified for retrofitting and/or strengthening. This study presents a simple screening procedure, based on the concept of Shiga Map, which considers the cross-sectional areas of RC columns and masonry infills, and their shear strengths as well as corresponding seismic demand. This procedure is further improved by incorporating the effects of secondary factors such as plan irregularities and presence of soft story, which have influences on the seismic behavior. |
