摘要
通过12根HDPF纤维带加固钢筋混凝土柱偏心受压构件试验,研究不同的包裹形式、不同层数、不同偏心距等因素对钢筋混凝土柱性能的影响。结果表明:HDPF纤维带可以有效约束核心混凝土,其极限承载力和延性二者都得到了不同程度的改善,其中包裹形式、包裹层数对加固效果影响较为明显。
By the eccentric compression test of 12 HDPF fiber reinforced concrete columns,the effects of different package form,different layers and different eccentricity on the performance of reinforced concrete columns are studied. The results show that wrapped HDPF fiber can effectively constrain the core concrete and improve the ultimate bearing capacity and the ductility of the members. The package forms and the numbers of layers play an important role in the strengthening effect.
