地震区多层异形框架柱-框架结构体系应用研究

摘要
异形框架柱-框架结构是由异形框架柱、普通矩形框架柱和框架梁组成的现浇钢筋混凝土框架结构。对等效长宽比不同的竖向异形截面构件分别按柱计算和按墙计算的差别进行了计算分析,基于周期、层间位移值、基底剪力及倾覆弯矩等主要动力指标和构件在水平力作用下变形特点认为长宽比为3～6的异形截面竖向构件在以框架为主体的多层结构中按异形框架柱进行计算和设计是可行的,并给出了该类构件按框架柱设计和按剪力墙设计的区分原则。振动台试验证明了异形框架柱-框架结构体系的安全性能。文中所给的2个工程实例可为类似结构设计提供参考。
The special-shaped frame column structure system can be defined as the reinforced concrete structure which is composed of concrete special-shaped frame column,ordinary frame column and beam.The differences between vertical special-shaped section components calculated as column or shear-wall are analysed by computer program.Based on main dynamical indexes of natural vibration period,interstory drift,base shear,overturning moment and deformation feature of a frame structure under horizontal force,it is feasible for the frame structure to calculate and design special-shaped section vertical components as special-shaped column whose equivalent length width ratio is from 3 to 6,and the distinguish principle for the types of components designed as the column or the shear-wall is presented.The shaking table model test has shown the safety capability of the special-shaped frame column structure system.Two engineering examples in the paper can be referred in similar structure design.
