摘要
对于高层结构的抗扭设计,现行抗震规范在结构布置、扭转作用、扭转刚度、抗扭承载力等方面都有所考虑。本文就其中的扭转位移比、扭转周期比、扭转刚度和扭转地震作用做一些讨论。建议应进一步研究扭转地震动和扭转地震作用下结构的弹塑性反应。
The code of seismic design of buildings have proposed some requirements and control measures about torsional design of structures.In this paper,the torsional displacement ratio,the torsional period ratio,the torsional stiffness and the torsional earthquake excitation are discussed.It is considered that the further study of torsional earthquake and elastic-plastic torsional response of structure should be made.
