异形柱框架结构的受力性能研究
|
摘要
从理论上分析了异形柱框架结构的扭转问题,建立异形柱框架结构的实体模型,分析其中的L形截面柱的受力性能。结果表明,在水平荷载(地震作用或风荷载)作用下,异形柱框架结构的抗扭性能良好;结构对称时,在单向水平荷载作用下,L形截面柱主要发生平行于水平荷载方向的位移,截面无扭转,且符合平截面假定,但L形截面柱的受力却是双向偏压,且截面中性轴沿柱高旋转变化。
Torsion problem of special-shaped column frame structure was analyzed theoretically,and a solid model of special-shaped column frame structure is set up to analyze mechanical behavior of L-shape section column;The result shows that torsional behavior of special-shaped column frame structure under a horizontal load is good;When structure is symmetric and under a single-direction horizontal load,the displacement L-shape section column is mainly parallel to the horizontal force direction,the section does not have a torsion,also tallies with the assumption of plane section,but the mechanical behavior of L-shape column is biaxial eccentric compression,also section neutral axis changes along column height with rotation.
