Configurations of spine frames in high-rise buildings, including two-segment spine frames, three-segment spine frames, partial spine frames, and conventional shear wall system were compared and discussed. Theoretical explanation for the optimal range of key structural parameters was illustrated by investigation on the simplified structural models.Seismic evaluation method considering higher-modes effect has been primarily developed for high-rise buildings. The evaluated results showed good agreement with the time-history analysis of the extensive parametric study conducted in this year, and the critical assumptions involved in the nonlinear modal pushover analysis are verified by modal time-history analysis.a simple design procedure has been proposed for the high-rise buildings adopting continuous or segmented spine frames. Detailed design chart is available for determination of the suitable spine configurations and value of the key structural parameters.Results of this research have been summarized in the doctoral thesis of this researcher. Essential results of this year were summarized in one international journal paper, which has been accepted and under production, and will be presented in domestic and international conferences. The research results are expected to provide an overall understanding on the seismic behavior of the low-damage, high robust controlled spine frame system. The simple design methods along with clear recommendations on key structural parameters are expected to be helpful for engineers to apply the proposed system in new building constructions.
