Construction Sequence Analysis for Checking Stability in High-Rise Building under Construction

초고층 건물의 시공 중 안정성 검토를 위한 시공단계해석

Due to recent trends of the atypical plan shapes and the zoning construction in high-rise buildings, the building stability under construction is arising as an important issue for design and construction plan. To ensure the stability under construction, the differential column shortening and the lateral movements with unbalanced distributions of self-weight of structure members and the load flows before completion of member connections and lateral load resisting system should be checked by construction sequence analysis. This paper presents the scheme of zone-based construction sequence analysis, to check the stability of high-rise building under construction. This scheme is applied to the construction sequence analysis for real high-rise building under construction.
