Abstract
This study presents optimal compensation algorithm of differential column shortening for more than two column groups. The proposed algorithm produces the minimum story groups and their compensation thicknesses which satisfy constraint conditions on performance and construction and enables not only the relative compensation but also the mixed compensation considering absolute shortening. The simulated annealing algorithm is used as the main optimization technique. The applicability of the proposed algorithm was verified by applying it to the 61-storey building where compensation of differential column shortening had already been performed. Using, the proposed algorithm compensation was performed easily and the number of compensation was less than the field method.
