| 摘 要： | 为研究偏心距对钢-连续纤维复合筋(SFCB)混凝土柱的受压性能,对7根混凝土强度等级为C35的SFCB混凝土柱进行静力受压试验,其中纵筋采用内芯钢筋6mm外包BFRP的SFCB。分析了偏心距对试件承载力、挠度、裂缝及破坏形态的影响。研究表明,偏心距越大,柱中挠度越大,最大裂缝宽度越大,极限承载力越小。

| Abstract: | In order to study the compression behavior of concrete column reinforced with steel-FRP composite bar,seven SFCB concrete columns with strength grade C35 are tested under static compression,in which the longitudinal reinforcement is SFCB with 6 mm inner steel bar and outer BFRP.Meanwhile,the effects of eccentricity on the bearing capacity,deflection,cracks and failure modes are analyzed.The result shows that with the increase of eccentricity,the deflection in columns and crack width increase while the ultimate bearing capacity decreases. |
