天长文化艺术中心大跨度连体钢结构分析与设计

Structural Analysis and Design of Large-Span Conjoined Steel Structure of Tianchang Culture and Art Center

天长文化中心建筑造型为盛开的茉莉花形状,三个单体与大跨度空中连廊通过隔震支座相连。阐述了连廊结构布置以及连廊支座形式选择,对带连廊整体模型和不带连廊多塔模型进行对比分析,主要包括小震作用下的加速度、位移和构件内力等,并通过设置TMD多模态减振系统进行减振设计,有效解决了大跨度连廊在人行荷载下的舒适度问题。

The figure of Tianchang Culture and Art Center is in the shape of a blooming jasmine flower.Three buildings are connected with a large-span aerial corridor by seismic-isolating bearings.The structural layout of the corridor and the bearing form of the corridor are introduced,the overall model with the corridor and the multi-tower model without the corridor are compared and analyzed,including acceleration,displacement,and internal forces in structural members.By setting the TMD multi-mode damping system for vibration reduction design,it effectively solves the human comfort problem of large-span corridor under pedestrian load.
