摘　　要：本文提出一种适用于结构中部大空间、局部楼板大开洞要求的新型超高层结构体系———多筒巨型柱框架体系。通过对计划采用该种结构体系的某超高层建筑进行三维有限元分析,研究了多筒巨型柱框架体系的动力特性、地震反应规律以及筒与筒之间不同刚度连接的影响,初步结果表明多筒巨型柱框架体系使用于低烈度区的超高层建筑是适宜的。In this paper, a new super high rise structural system, known as the multitube megacolumn frame system, which can be applicable to buildings with large space in central part and local openings in floors is proposed. By means of three dimensional finite element analysis of a super high rise building using multitube megacolumn frame structural system, the dynamic properties, the rules of seismic responses and influences on dynamic properties caused by different stiffnesses of connecting members among tubes have been studied. Preliminary results illustrate the suitability in application of the multitube megacolumn frame system in low earthquake intensity regions.
