지지시스템을 고려한 철근콘크리트 골조 구조물의 시공단계별 해석

Abstract

Unlike the analysis and design of a reinforced concrete (RC) frame structure, which are conducted on the basis of a completed structure without considering any change in the structural system, the construction of an RC frame structure accompanies the sequential changes in the structural system and causes the actual structural behaviors which represent remarkable differences from those calculated in the analysis procedure. Accordingly, to simulate the actual structural behavior and to predict the exact structural responses, a rigorous numerical analysis considering creep, shrinkage, and construction sequence must be conducted. Upon these considerations a numerical model, which was introduced inn the previous study, is used in this paper for the analysis of RC frame structures. Many correlation studies with the purpose of analyzing the time-dependent behavior of building structures are conducted. In advance, the influence of shoring systems on the structural behavior is reviewed, and the importance for the analysis of RC frame structures considering the construction sequence and shoring systems is emphasized.
