中文摘要：
框架-混凝土核心筒混合结构在我国已得到广泛应用,但对其水平位移限值的研究尚不完善,还存在诸多问题。通过理论分析和有限元计算,讨论了高宽比对结构变形的影响,明确了高宽比与位移限值间的相关性。通过四个算例的位移特性和安全性的比较,认为相对层间位移角和顶点位移角可以作为层间位移角的有效补充,而且当外围框架类型不同时,宜视位移指标不同给出相应的位移限值。
英文摘要：
Frame-concrete corewall hybrid structure is widely used in China,but research on horizontal drift limit is not fully addressed.Based on theoretical analysis and finite element analysis,influence of height-width ratio on structural deformation was discussed and the relationship between height-width ratio and drift limit was illustrated.Furthermore,drift and safety of four frame-concrete corewall hybrid structures were compared.As a result,relative inter-story drift and roof drift can act as effective supplements of inter-story total drift,and drift limit should be determined according to different drift index for structures with different peri-frame type.
