摘要:
《建筑隔震设计标准》(后简称《隔标》)是我国第一部专门指导隔震设计的国家级标准。由于目前基于新规范完成隔震设计的实际工程较少,尤其是百米级高层隔震结构在我国还尚属少见,为此针对某百米级住宅公寓楼实际工程展开研究,根据《隔标》完成隔震设计,并从经济性的角度出发,对比了一体化直接设计法与传统分部隔震设计法的配筋结果;最后结合现行规范对高层隔震结构的风振舒适度进行了评估。研究结果表明:一体化直接设计方法在显著提升隔震结构安全的同时还具有较好的经济性,即使隔震结构设防目标由小震提升至中震,即地震作用提升约3倍的前提下,该高层隔震结构总用钢量的增加仍控制在15%以内;百米级高层隔震结构在1年、10年风荷载作用下均出现了舒适度问题,最大风振加速度响应分别达到了10.3gal和18.0gal,超出规范限值71.7%和20%,在未来的隔震结构抗风设计中,高层隔震结构的风振舒适度问题应引起足够重视。
Abstract:
" Standard for seismic isolation design of buildings " is the first national standard to guide isolation design in China. At present,there are few practical projects to complete the isolation design based on the new code, especially the 100-m-level high-rise seismically isolated structure is rare in China. Therefore,this paper studies the actual project of a 100 m residential apartment building, completes the isolation design according to the "Standard for seismic isolation design of buildings ", and compares the reinforcement results of integrated direct design method and traditional divisional design method from the perspective of economy; finally, combined with the current code,the wind-induced vibration comfort of high-rise seismically isolated structure is evaluated. The results show that the integrated direct design method not only significantly improves the safety of the seismically isolated structure,but also has good economy. Even if the fortification target of the seismically isolated structure is raised from small earthquake to medium earthquake,that is,the seismic action is increased by about 3 times,the increase of the total steel consumption of the high-rise isolated structure is still controlled within 15%;the comfort problem of 100-m-level high-rise seismically isolated structure under 1-year and 10-year wind load occurs,and the maximum wind-induced acceleration response reaches 10.3 gal and 18.0 gal respectively,which exceedes the code limit by 71.7% and 20%. In the future wind resistant design of isolated structures,enough attention should be paid to the wind-induced vibration comfort of high-rise seismically isolated structure.
