The Capacity Design Method towards Improving Seismic Perfor mance of Gravity-Load Designed R/C Frames

내진역량설계법(Capacity Design Method)을 이용한 비내진설계 R/C 골조의 내진 성능 향상기법

The seismic performance of R/C frame structure designed for gravity load investigated in this paper. The investigation shows a satisfactory seismic performance against moderate earthquakes but column sway failure mechanism against severe earthquakes. Capacity design method is employed to redesign the R/C frame to improve seismic performance. This study provides an insight an insight into seismic upgrading methodology for medium rise R/C frame structures designed gravity load.
