Module-core tube structure capable of timely tuning and damping
The module-core tube structure comprises a reinforced concrete core tube, and prefabricated steel modules are arranged on the periphery of the core tube; a certain gap is formed between the two parts, and the two parts are horizontally connected at different heights through a mechanical hinge, a spring and a slidable floor with a brittle limiting block respectively. The multiple layers of prefabricated steel modules are vertically stacked, and a plurality of adjacent layers of steel modules form a module group through interlayer connection; and a laminated rubber support and a viscous damper are arranged between the vertically adjacent module groups. The module groups are divided into module groups A and module groups B according to whether the tops of the module groups are hinged to the core tube or not, the module groups A and the module groups B are vertically arranged at intervals, and the uppermost module group is limited to be the module group A; when an earthquake comes, the module group A and the module group B are matched to realize grouped rapid disconnection of the brittle limiting blocks and timely change the structure configuration, through reasonable spring stiffness and viscous damper parameters, tuning damping of the module groups and the core tube structure is realized, and the problem that tuning of the structure is not timely is solved.
本发明公开一种及时调谐减震的模块‑核心筒结构，包括钢筋混凝土核心筒，并在核心筒周围设置预制钢模块；两者之间有一定间隙，在不同高度处分别通过机械铰、弹簧、带有脆性限位块的可滑动楼板进行水平方向的连接。多层预制钢模块竖向堆放，相邻的若干层钢模块通过层间连接形成模块组；竖向相邻的模块组之间设置叠层橡胶支座和粘滞阻尼器。根据各模块组是否在其顶部与核心筒铰接分为A、B模块组，两者沿竖向间隔布置，并限定最上方为A模块组。在地震来临时通过A、B模块组配合实现脆性限位块的分组快速断开，及时转变结构构型，通过合理的弹簧刚度和粘滞阻尼器参数，实现模块组和核心筒结构的调谐减震，克服此类结构调谐起效不及时的问题。
