摘要
异型柱框架结构是一种新型节能结构,空间布置灵活,被广泛采用多层和小高层结构.基于振型分解法,采用ANSYS软件建立异形柱与矩形柱框架结构空间模型,从结构周期、弹性层间位移角、轴力及轴压比等方面进行分析比较.结论和建议对设计和施工具有一定指导意义,为该结构体系的进一步发展提供理论依据.
Special-Shaped Column Frame is a new structure with space-free,it is widely used in multistoried and moderate high-rise buildings.Based on mode analysis method,establish space models of specially shaped and rectangle column frame structure with ANSYS software,analyze and compare natural vibration period,elastic displacement between floors,axial force and equivalent axial load ratio.The conclusion and suggestion are of supervision to engineering design and construction and can provide theoretical basis for further development.
