翼缘框架柱框架结构的动力特性

对具有不同截面长度翼缘构件的翼缘框架柱框架结构进行了弹性动力特性分析，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，并以工程实例及其结构振动台试验对翼缘框架柱框架结构体系的安全性能进行了验证。结果表明：等效截面长宽比为3～6的异形截面竖向构件在以梁、柱等杆件单元为主体的框架结构中按框架柱设计是可行的，翼缘框架柱框架结构体系具有足够的安全性能，可以在抗震设防区的多、高层建筑中应用。

Dynamic Characteristics of Flange Frame Column Structure

Elastic dynamic characteristics analyses of flange frame column structure with different length flange components were carried out, and the distinguishing principle which this type of component was designed as frame column or shear-wall was given. The engineering example and its shaking table test were used to prove the safety capability of flange frame column structure system. Results indicate that it is feasible in frame structure that designs special-shaped section vertical component as column whose equivalent section length-to-width ratio is from 3 to 6. Moreover, the flange frame column structure system has enough safety capability and can be applied to seismic fortification region in high-rise buildings.
