The invention discloses a frame-core tube structure capable of rotating during strong earthquake, and relates to the technical field of structural engineering. The bottom end of the core tube is connected with a foundation through a rotating support, the rotating support comprises a rotary table seat fixed to the top face of the foundation, an arc-shaped groove is formed in the top face of the rotary table seat, a rotating ball is fixed to the bottom end of the core tube, and the lower portion of the rotating ball is rotationally arranged in the arc-shaped groove. The frame part consists of frame columns and frame beams and is arranged around the outer side of the core tube; the joint part comprises beam end joints and column base joints, the beam end joints connect the ends of the frame beams with the frame columns and the core tube, and the column base joints connect the frame columns with the foundation. The problem that due to external excitation such as the earthquake action, a traditional frame-core tube structure forms plastic hinges at beam-column joints, column feet, the bottom of a shear wall and the ends of the two sides of a connecting beam to dissipate earthquake energy, and consequently structural components cannot be normally used can be solved.
本发明公开了一种强震时转动式框架‑核心筒结构，涉及结构工程技术领域，包括基础；核心筒的底端通过转动支座与基础连接，转动支座包括固定在基础顶面的转台座，转台座顶面开设有弧形凹槽，核心筒底端固定有旋转球体，旋转球体的下部转动设于弧形凹槽内；框架部由框架柱和框架梁组成，且环绕核心筒外侧布置；节点部包括梁端节点和柱脚节点，梁端节点分别将框架梁的端头与框架柱和核心筒连接，柱脚节点将框架柱与基础连接。本发明可解决因地震作用等外部激励致使传统框架‑核心筒结构在梁柱节点处、柱脚处、剪力墙底部以及连梁两侧端部形成塑性铰耗散地震能量，从而导致结构构件不能正常使用的问题。
