某带强连接钢连廊高层建筑结构抗震性能化设计与分析
Seismic Performance-Based Design and Analysis of a High-Rise Building Structure with a Strong Connected Steel Corridor
某带强连接钢连廊高层建筑结构地上5层,地下1层,建筑高度为26.2 m,采用框架-剪力墙结构体系。结构同时具有扭转不规则、楼板不连续及构件间断共3项不规则项,属于规则性超限高层建筑。针对不规则项,采取了相应的加强措施。为保证结构设计合理,采用YJK、MIDAS Building和SAUSAGE三种软件对结构进行了多遇地震和风荷载作用下的弹性反应谱分析、多遇地震作用下的弹性时程分析、设防地震和罕遇地震作用下的等效弹性分析、罕遇地震作用下的弹塑性时程分析。重点介绍了作为“关键构件”的强连接体的构造、为确保塔楼间协调变形及解决强连接体带来层间刚度突变问题所采取的技术措施。为保证强连接钢连廊的安全,补充了相关专项分析。计算结果表明,采取相应的加强措施后,结构各项计算指标均能满足规范要求,能够达到预设的抗震性能目标。
The high-rise structure with a strongly connected steel corridor comprises five above-ground floors and one underground floor, with a building height of 26.2 m, and adopts a frame-shear wall structural system. The structure exhibits three types of irregularity: torsional irregularity, discontinuous floors, and discontinuous structural components, thereby categorizing it as an out-of-code irregular building. Corresponding strengthening measures have been implemented to address these irregularities. To ensure the rationality of the structural design, elastic response spectrum analysis under frequent earthquakes and wind loads, elastic time-history analysis under frequent earthquakes, equivalent elastic analysis under fortification-level and rare earthquakes, and elasto-plastic time-history analysis under rare earthquakes were carried out using YJK, MIDAS Building, and SAUSAGE software. This paper focuses on the configuration of the strong connection as the key component, detailing measures to ensure coordinated deformation between the towers and to mitigate the effect of sudden stiffness changes induced by the strong connection. Specialized analyses were also conducted to ensure the safety of the strongly connected steel corridor. The results demonstrate that, after implementing the corresponding strengthening measures, all structural performance indices satisfy the code requirements, meeting the expected seismic performance objectives.
