Carbonstäbe im Bauwesen – Teil 5: Einflussfaktoren auf das Verbundverhalten

Abstract: Nachdem in den vorherigen Veröffentlichungen dieser Publikationsserie die Grundlagen beschrieben sowie die ersten Vorversuche zum Verbundverhalten von Carbonstäben veröffentlicht wurden, folgt in diesem Beitrag die Darstellung wesentlicher Einflussfaktoren auf das Verbundverhalten von carbonstabbewehrten Betonbauteilen. Für eine ausgewählte Stabvariante – einen Carbonstab mit einer gefrästen Oberflächenprofilierung – werden konkret die Einflüsse von Betonfestigkeit und Verbundlänge auf das Verbundverhalten exp… Show more

“…In Figure 1, a typical failure mode of a carbon rebar from a pull-out test is shown. For more information on the bond behavior of non-metallic and steel rebars in general, see [5,[11][12][13][15][16][17][18][19][20][21][22][23].…”

“…In Figure 1, a typical failure mode of a carbon rebar from a pull-out test is shown. For more information on the bond behavior of non-metallic and steel rebars in general, see [5,[11][12][13][15][16][17][18][19][20][21][22][23]. However, the lack of standardized geometric characteristics for carbon rebars poses challenges in understanding and predicting their bond behavior.…”

“…A promising approach for improving the mechanical performance of TRC by creating a dominant shear bond is the profiling of the reinforcement structure. For rigid fiberreinforced plastic (FRP) rebars with large cross-sections, additive and subtractive profiling methods are established, such as additive wrapping of an additional helix structure, the application of anchoring structures such as plastic ribs, or the subtractive milling of a rib-like structure [32][33][34]. Decisive for the effectiveness of the form fit is its durability, as well as the (composite) strength between roving and cover/anchoring [35,36].…”
