Prediction and Evaluation on Inequality Shortening and Long-term Deflection of High-rise Flat Plate Structure using 3D Finite Element Analysis

3차원 유한요소해석을 이용한 고층 무량판 슬래브 구조물의 부등축소량 및 장기처짐 예측 평가

Flat plate structures are designed in the form of long span due to the development of construction materials and the improvement of construction technology. However, a high-rise structure of a flat plate of 50 less floors is constructed without detailed review of the inequality shortening, long-term deflection of the slab, and cracks. Therefore, it is possible to examine the case of defects in the structure due to deformation and damage of non-structures such as crack and leak, deflection of the door frame, and deformation of equipment ducts. In this study, it is a high-rise structure, and the inequality shortening and long-term deflection of the slab of the flat plate structure were evaluated through finite element analysis, and it was confirmed that prior precision analysis and correction during construction is necessary.
