TY - JOUR AU - Baitian Wang, Hongjuan Zhao, Qiyu Li, Junjie Sun, D.C.Zhang, PY - 1970/01/01 Y2 - 2024/03/29 TI - Safety Analysis of Formwork Fystem in Core Tube Construction of Super High-rise Building JF - Forest Chemicals Review JA - JFCR VL - IS - SE - Articles DO - UR - http://forestchemicalsreview.com/index.php/JFCR/article/view/1021 SP - 1521-1543 AB - Taking the formwork system in core tube construction of a super high-rise building project as the research background, taking the fixed load combination value according to the Load Code for the Design of Building Structures, combined with different construction stages and wind load directions, considering the failure and sinking of a single-piston rod by 100mm, 45 working conditions are determined. The finite element model of the jacking formwork system is established on ANSYS. The permanent load, live load , wind load are determined in detail. The safety of the formwork system during the construction of the core tube is evaluated from the three aspects of strength, stiffness ,stability. According to the analysis results, it is determined that the formwork system is safe during the construction process. The support reaction of the model structure is extracted. Based on the analysis results, the suggestions in the construction process are put forward, which lays a foundation for the safe design and construction of the core tube formwork system. ER -
