摘要:
纤维聚合物筋与钢筋性能的差异,使纤维聚合物筋混凝土的粘结性能与钢筋混凝土的粘结性能存在明显不同.根据纤维聚合物筋与混凝土之间的传力机理,讨论了粘结应力、纤维聚合物筋应力以及锚固长度之间的关系,建立了纤维聚合物筋混凝土粘结计算的基本公式.在总结国内外已有的纤维聚合物筋与混凝土粘结滑移本构模型的基础上,提出了粘结滑移的连续曲线本构模型.该模型以粘结滑移曲线的三个关键点为基础,物理概念明确、光滑连续.最后,讨论了锚固长度的计算问题,建议了锚固长度的计算方法.
Abstract:
The difference in the properties of fiber polymer reinforcement and steel bar makes the bonding performance of fiber polymer reinforced concrete significantly different from that of reinforced concrete. According to the force transmission mechanism between fiber polymer reinforcement and concrete, the relationship between bonding stress, fiber polymer reinforcement stress and anchorage length is discussed, and the basic formula for calculating the bonding of fiber polymer reinforced concrete is established. On the basis of summarizing the existing bond-slip constitutive models of fiber polymer reinforcement and concrete at home and abroad, a continuous curve constitutive model of bond-slip is proposed. The model is based on the three key points of the bond-slip curve, and the physical concept is clear, smooth and continuous. Finally, the calculation of anchor length is discussed, and the calculation method of anchorage length is suggested.
