Abstract |
In Korea, the importance of seismic design for non-structural elements has been highlighted due to recent earthquake damage cases in Gyeongju and Pohang. In this study, for the non-structural seismic design of high-rise RC wall-type structures mainly used in residential buildings in Korea, design codes were investigated and analysis on the maximum floor acceleration of high-rise RC wall-type structures was conducted through nonlinear seismic analysis. According to the nonlinear analysis, in high-rise RC wall-type apartments, the amplification of the acceleration for each floor of the structure does not show a linear amplification as in the design codes. In particular, it can be seen that the acceleration amplification appears large in the middle floors, and the acceleration amplification is different even within the same plan. In the case of high-rise RC wall-type apartments, the higher-order natural mode corresponding to the 4th to 6th mode has a great influence on the acceleration amplification, and the acceleration amplification in the same floor has a significant difference due to the rectangular plan shape.
