摘要
对设置有偏心支撑的轴压构件,采用瑞利里兹法研究其偏心距大小对构件屈曲承载力的影响。经讨论发现,对于双轴对称截面的轴压构件,侧向支撑存在偏心时会降低其屈曲承载力,产生不利影响;相反对于单轴对称的截面,支撑的偏心却能够提高轴压柱子屈曲时的承载力。
This paper is about the effect of the eccentricity on the column by using the Rayleigh-Ritz method . It is found that the eccentricity of the support could reduce the buckling capacity of the column with a doubly symmetric section. Otherwise the eccentricity of the support could improve the buckling capacity of the column with a single symmetrical section.
