Research on seismic isolation structure design of gymnasium building in high seismic intensity area

合理地应用隔震技术可保证建筑在中、大震后的正常使用性能,对高烈度区体育馆建筑具有较强的适用性。以唐山新体育中心体育馆为例,对高烈度区体育馆建筑进行隔震设计研究。首先,对此体育馆进行刚性结构方案和隔震结构方案比选,以证明此体育馆采用隔震结构方案可减小构件截面尺寸、增大建筑使用空间,同时降低工程造价。其次,着重讨论了隔震层开洞、黏滞阻尼器布置及其位置等问题,通过在隔震层比赛场地区开洞且沿洞口周边布置黏滞阻尼器的方式,在实现经济性的同时保证隔震层的整体性,为带比赛场地的体育馆类建筑隔震设计提供参考。最后,详细阐述此体育馆隔震设计的主要计算结果,证明隔震技术在此项目中应用的有效性和安全性。

By reasonable application, seismic isolation technology can ensure the normal service performance of building after fortification or rare earthquakes, and it has strong applicability to gymnasium buildings in high seismic fortification intensity areas. Taking Tangshan Gymnasium as an example, the seismic isolation structure design of the gymnasium building in the high seismic fortification intensity area was researched. Firstly, the rigid structural scheme and the isolation structural scheme of the gymnasium were compared, and it proves that the isolation structural scheme reduces the member section size, increases the architecture use space and decreases the cost. Secondly, the isolation layer opening, the arrangement and location of viscous dampers were mainly discussed. By setting openings at the playing field on the isolation layer and arranging viscous dampers around the openings, the economy was achieved while the integrity of the isolation layer was ensured, which could provide reference for the isolation design of gymnasium buildings with playing fields. Finally, the main calculation results of the seismic isolation design of the gymnasium were elaborated, proving the effectiveness and safety of the seismic isolation technology used in this project.
