| 摘 要： | 以一幢位于8度抗震设防区域的超限超高层建筑为案例，针对所设定的承载力、变形及损伤控制等抗震性能目标，建立了精细的结构非线性有限元计算模型，采用弹塑性动力时程方法分析和评估了与性能目标相对应的结构动力响应和损伤状况。结果表明，通过将性能设计与结构动力时程精细分析相结合，能够实现使不同受力构件达到不同的抗震性能需求的目的，从而使得超高层建筑的抗震设计更具精细性和预见性。

| Abstract: | A code-exceeding super high-rise building located at the 8 degree seismic fortification in- tensity region was taken as an example, and a refined nonlinear finite element computational model for the building structure was established aiming at the predefined seismic performance objectives including load capacities, deformation and damage controls. The elastic-plastic time-history analysis procedure was then employed for determination and assessment of the dynamic responses and damage conditions corre- sponding to the performance objectives of the structure. The analysis results demonstrate that the eom- bined use of performance-based design and refined pose for different load-bearing members sign for super high-rise buildings to a hi dynamic time-history analysis could realize the pur- reaching different performance demands, leading the seismic de- gher level with more refinement and precaution. |
