Construction Stage Analysis of Column Shortening applying to the Top-Down Method in Tall Buildings
초록
영어
Long-term deformation of vertical members in tall buildings can cause structural and serviceability problems by causing differential column shortening between vertical members. Therefore, it is necessary to analyze the differential column shortening through the construction stage analysis assuming the actual construction process. In particular, unlike the general construction process, the top-down method has the characteristic that the slab is installed before the column, so caution is needed in the analysis of the construction stage. In this study, we intend to propose a method for differential column shortening in which the top-down method is applied to the construction stage analysis.
