摘要：本文对7根PEC柱进行了弱轴方向偏心受压试验，主要考虑了翼缘宽厚比和偏心距这两种因素的影响。试验结果表明：随着偏心距的增大，偏心受压构件的极限承载能力降低；随着翼缘
宽厚比的减小，偏压构件的极限承载能力有所提高；偏心距对构件的极限承载能力影响较大。

Abstract: Eccentricity compression test on 7 welding H steel partially encased concrete composite columns in weak axis were studied, mainly considering the effect of flange width thickness ratio and eccentric distance. The results showed that with the increase of eccentricity, the ultimate bearing capacity of eccentric compression member decreased; with the decrease of the flange width thickness ratio, the limit of bearing capacity of eccentrically compressed members increased; and the eccentricity had a greater influence on the ultimate bearing capacity of the components.
