[提要] 用沿高度方向分段連續(xù)化的方法，對底部為大底盤、上部為多塔縷、塔摟圊帶連廊的高層建筑結構，建立一個分段連續(xù)的串并聯(lián)模型，導出其在水平荷載作用下的平衡微分方程組。用常微分方程求解器COLSYS求解其位移和內(nèi)力。為復雜結構設計提供了一種簡化的算法。
[關鍵詞] 高層建筑結構 大底盤多塔樓 帶連廊By using the commonly used continuum technique,a new piecewise continuous series - parallel connection model is taken as the computational model for the multi- tower structure linked by spatial corridors and with enlarged base at the bottom. Then, the differential equations of equilibrium for the model are derived. Moreover, the displacements and internal forces of the structure are determined numerically by means of the ODE (Ordinary Differential Equation) solver, which is a program developed for solving various ODEs.
Keywords: tall building structure; multi- tower; enlarged base; spatial corridors
