In this paper, the seismic response control of BRBs in super high-rise RC buildings subjected to earthquake ground motions is investigated by nonlinear time history analysis. The analysis model is a 36 stories super high-rise RC building. A bare frame structure is used as a reference model. The parameter of the analysis was the configuration of the BRBs. Two kinds of seismic response controlled building models were examined. In one model, the RC frame was braced by BRBs in each story (each model) and in the other one, each BRB spanned over two stories (over model). The RC beams in the braced span of the over model were abandoned. By comparing the maximum story drift ratio of the reference model with the braced ones, the seismic response control was confirmed for both the each model and the over model. In addition, the over model exhibited almost the same seismic response control as compared to the each model, although the number of BRBs was significantly reduced and the RC beams in the braced span were abandoned.

This report presents studies on the seismic response of high-rise RC buildings in Japan. Data concerning the seismic response of approximately 600 high-rise RC buildings constructed from 1972 to 2015 were collected. Seismic response characteristics were analyzed by focusing on differences in seismic resistant structures, seismic response control structures, and seismic isolation structures. The results indicated that the maximum story drift ratio response under the level 1 study seismic ground motion (R) and the level 2 study seismic ground motion (R) criteria is smaller for seismic isolation structures than that of the seismic resistant structure and seismic response control structures. In addition, focusing on the R-R relationship, the correlation is low in the seismic resistant and seismic response control structures, but is almost linear in the seismic isolation structure. This is because the seismic isolation structure is designed such that the superstructure does not become plastic even with level 2 seismic ground motion.
