ƒ^ƒCƒgƒ‹i‰pjF Evaluation of Seismic Drift Demand for RC Buildings with Weak First Story Based on Story Strength Ratio
´˜^i‰pjF It is known that seismic drift demand for RC buildings with weak first story is affected not only by the strength of the first story but also the strengths of the second story and above. In this study, the dynamic response analyses where the first story strength and strength ratio of the first story to the second story and above were considered as analysis parameters. Based on the study, the relations between the first story strength and second story strength required to limit the first story drift demand within a given level were presented. The prototype structures to be studied were six- and fourteen-story RC buildings with the weak first story designed for the study.
