本文针对高层建筑实腹开洞筒体,选择独立的结构模型和计算单元,不同于当前流行的连续化模型和离散化模型.在引入“连梁影响系数”概念的基础上,首先为实腹开洞筒体建立了系统的约束扭转理论,继而为高层建筑开洞筒体的整体内力和位移分析提供了一个统一的方法——“位移递归法”.算例和现有模型实验的对比表明:新的理论和方法在计算精度、计算速度和对微机的内存要求方面有着显著的优越性.
This paper focuses on the construction of real-epit boreholes for high-rise buildings and selects independent structural and computational units, which are different from the current popular continuous and discrete models. Based on the introduction of the concept of “coupling beam impact coefficients”, the first is the actual The open-ended cylindrical body establishes the system’s constrained torsion theory, and then provides a unified method for the analysis of the internal forces and displacements of the tall building’s open-ended canal—“Recursive displacement method”. The comparison between the example and the existing model experiment shows that : The new theory and method have significant advantages in terms of calculation accuracy, calculation speed, and memory requirements for the microcomputer.
