A Study on the Effect of Construction Time in the Column Shortening in High-Rise Building

초고층 구조물에서 기둥축소에 대한 시공기간의 영향에 관한 연구

Differential shortening of vertical members in high-rise buildings affect other structural members that have to be considered such as horizontal members and exterior cladding. of many elements which affect the total amount of shortening, different loading history mainly comes from the different construction time. Shortening of 66 story concrete columns were investigated and compared according to the different construction time, little difference was found between the total shortening of interior and that of exterior column.
