Tóm tắt
In this paper, an effcient procedure integrating the moving compensation optimization (MCO) and a modifed
differential evolution algorithm is presented for fnding the optimal solution to compensate for the differential
column shortening (DCS) in tall buildings. In the proposed compensation procedure, the number of compensation groups is minimized by maximizing the number of floors for each group stepwise with constraints placed on
the compensation error at each floor level. Two optimal compensation problems are presented, including the
deterministic optimal compensation (DOC) and the reliability-based optimal compensation (ROC), which
correspond to ignoring or considering the uncertainties that are inherent in the predicted shortenings as well as
the correction amounts. A parameter-free, adaptive differential evolution algorithm is established to solve MCO.
Applications for a 70-story building and a 72-story building are examined to demonstrate the effciency and
reliability of the presented compensation approach.
