为研究玄武岩纤维的加入对高强自密实混凝土长柱受力性能的改善作用，以玄武岩纤维体积掺量0.1%和0.2%、长度15 mm和30 mm为参数，设计制作了10个长细比为6的高强自密实混凝土长柱，进行偏心受压试验。结果表明：玄武岩纤维的加入，可明显改善高强自密实混凝土柱偏心受压的受力性能、延性；大、小偏心受压构件开裂荷载分别提升20.7%、11.8%，极限承载力最大增幅为18.2%、16.7%；大、小偏心构件受压过程中，玄武岩纤维的加入使应力峰值对应的混凝土应变受到较为显著的影响，当达到大极限承载力时，最大的拉、压应变下降25.0%、15.0%；由于玄武岩纤维的作用，大偏心受压试件达到极限承载力时，跨中最大挠度提升7.6%，提高了构件变形能力，但纤维长度、体积掺量改变引起的挠度效应不大。
In order to study the improvement of high-strength self-compacting concrete(HSCC) slender column after adding basalt fiber, ten HSCC slender columns in a slenderness ratio of 6 were designed for eccentric compression test, based on the parameters of basalt fiber volume in 0.1% and 0.2%, length in 15mm and 30mm.The results show that the addition of basalt fiber can significantly improve the stress performance and ductility of HSCC columns under eccentric compression. The cracking load of large and small eccentric compression members is increased by 20.7% and 11.8% respectively, and the maximum increase in ultimate bearing capacity is 18.2% and 16.7% respectively. During the compression of large and small eccentric members, the addition of basalt fiber has a remarkable impact on the concrete strain corresponding to its stress peak. When the maximum ultimate bearing capacity is reached, the maximum tensile and compressive strains are reduced by 25.0% and 15.0%; when the large eccentric compression specimens reaches the ultimate bearing capacity under the action of basalt fiber, the maximum deflection in the mid-span increases by 7.6%, which improves the member's deform-ability while has no big deflection effect by the change of fiber length and volume content.
