Formulation of an Optimal Compensation Method for Differential Column Shortening in Highrise Buildings

고층건물 기둥 부등축소량의 최적보정기법 정식화

Differential shortenings of columns in a highrise building must be considered in the design process to avoid unexpected damages in structural and nonstructural elements. While research activity has been reported in the literature on the development of estimation algorithms or prediction procedures of elastic and inelastic column shortenings, no algorithms or methods for compensation of differential shortenings. In this paper a compensation method for differential column shortenings in a high-rise is formulated as an optimization problem The simulated annealing algorithm is used to find optimal solutions. The performance of the proposed method is presented by using the well known examples developed by PCA.
