中文摘要:
      以抗震设防7度区的某高层钢框架结构建筑为研究对象,研究基于隔震就位连接技术的高层钢框架结构建筑抗震技术。对研究对象采用抗震就位连接技术,通过在隔震层中设置弹性滑板支座、厚层橡胶隔震支座化黏滞阻尼器等隔震装置提升研究对象自振周期,降低其上部结构受地震作用的影响程度,增强抗震性能。对研究对象进行模态分析与时程分析,结果显示,所研究隔震技术在显著提升研究对象自振周期,使其摆脱场地特征周期的同时,也能够延缓扭转振型的形成,显著降低地震作用对研究对象上部结构的影响,说明所研究技术的运用具有较好的抗震效果。
英文摘要:
      Taking a high-rise steel frame structure building in a 7-degree seismic fortification area as the research object, the seismic technology of high-rise steel frame structure buildings based on isolated-in-place connection technology was studied. Seismic in situ connection technology was used to increase the natural vibration period of the research building by setting elastic skateboard bearings, thick rubber isolation bearings, and viscous dampers in the isolation layer, so as to reduce the influence of earthquakes on the superstructure and enhance seismic performance. Modal and time-history analyses were carried out on the research building. Results showed that the proposed isolation technology only significantly improved the natural vibration period of the structure, but also delayed the formation of torsional vibration mode, significantly reducing the influence of seismic action on the superstructure of the research object. It was shown that the studied technology has a good seismic effect.
