【摘要】 | 广州中洲二期观光门工程整体结构属于体型复杂的超限结构。结合结构设计理念,在设计中采用了基于性能的抗震设计方法,利用多种分析手段验证不同水准下结构的抗震性能,包括小震弹性验算、中震弹性及中震不屈服构件验算,以及罕遇地震下的弹塑性时程分析。参考振动台试验,提出合理的结构抗震设计措施。同时,根据工程的风洞试验结果进行不同风向角下的风振时程分析,进行合理的结构抗风设计。还研究了粘滞阻尼器的设置对结构在内力、变形、加速度及能量方面的控制效果。通过以上及结构整体稳定、温度效应、楼板振动等大量计算分析,对结构提出了相应的超限设计措施,使结构能够更好地实现预定的性能目标。 |
【英文摘要】 | Zhongzhou Phase Ⅱ Project is an ultra-limit structure with hybrid structure system and complicated structural shape. Design idea of performance based seismic design was presented Seismic performance of the structure under different level of ground motion was analyzed and verified by different methods, such as elastic analysis under frequent earthquake, un-yield and elastic verification of structure element under medium earthquake and inelastic dynamic time-history analysis under rare earthquake. Taking result of shaking table test as a reference, reasonable enhance measures of seismic design were suggested based on analysis results. Meanwhile, wind-induced vibration time-history analysis under different wind directions based on wind tunnel test was applied and comfort problem can be well resolved. The vicious dampers’ control effect on inter force, deformation, acceleration and energy dissipation of the structure was also studied. By means of analysis methods mentioned above and other plenty analysis of the whole structure stability, temperature effect, floor vibration and so on, relevant measures of ultra-structure design were suggested and the performance objective of the structure can be well realized. Keywords: connected tall building structure; performance based seismic design; wind-induced vibration time-history analysis; vicious damper; stability analysis |
