Abstract
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.
