［摘要］GFRP管混凝土組合柱因其經(jīng)濟(jì)性和耐久性可適應(yīng)較惡劣的環(huán)境，但目前對GFRP管混凝土組合長柱的研究較少。通過對這種組合長柱試件進(jìn)行軸心受壓試驗與有限元數(shù)值分析，揭示不同組合形式對其受力性能的影響。結(jié)果表明，GFRP管的約束會明顯提高組合長柱試件的極限承載能力，且隨長細(xì)比的增大，承載力的提高幅度下降；GFRP管的纖維纏繞角度也會對組合長柱試件的軸向承載能力和變形剛度產(chǎn)生影響。

Abstract:The concrete\|filed GFRP tube composite column can adapt to the worse environment because of its economy and durability, but the research on the long concrete\|filed GFRP tube composite column is few. Through the axial compression test and finite element numerical analysis, the influences of different combination forms on the mechanical properties of this type of long composite column were revealed. The results show that the ultimate bearing capacity of long composite column can be obviously improved by the constraint of GFRP tube, and the increment of the bearing capacity decreases with the increase of slenderness ratio. The winding angle of GFRP tube also affects the axial bearing capacity and deformation stiffness of long composite column.
Keywords:long concrete\|filled glass fiber reinforced polymer(GFRP) tube composite column; axial bearing capacity; fiber axial deflection; winding angle
