Novel FRP confined concrete column

Abstract

The invention discloses a novel FRP confined concrete column. The novel FRP confined concrete column comprises a concrete core which is cylindrical and an FRP sleeve sleeving the concrete core. The FRP confined concrete column further comprises an anti-crack material layer arranged between the concrete core and the FRP sleeve, the anti-crack material layer is made of anti-crack materials, and the anti-crack material layer can generate a plurality of micro-cracks when the concrete core generates local large cracks due to the fact that the concrete core bears compression loads, so that local stress and strain are redistributed. According to the novel FRP confined concrete column, the FRP confining efficiency and the overall structural performance can be improved. 公开了一种新型FRP约束混凝土柱。新型FRP约束混凝土柱包括：混凝土芯，所述混凝土芯具有柱形；FRP套管，所述FRP套管套住所述混凝土芯。所述FRP约束混凝土柱还包括设置在所述混凝土芯和所述FRP套管之间的抗裂材料层，所述抗裂材料层由抗裂材料制成，所述抗裂材料层能够在所述混凝土芯因承受压缩载荷而产生局部大裂纹时，产生多个微裂纹，从而重新分配局部应力和应变。所述新型FRP约束混凝土柱可以提高FRP约束效率以及整体结构性能。
