Case study

Abstract. The purpose of this article is to confirm an accuracy of Cohesive Zone Model (CZM) implemented in Ansys for modelling concrete beams strengthened with fiber reinforced polymer (FRP) tapes. Only mode II of debonding was taken into account, which is sufficient for a case of bent beam strengthened with FRP tape glued to its bottom. Results show satisfying coincidence of used model with experimental data and therefore confirm usefulness of CZM for solving the above mentioned problems.
Keywords: concrete structures; finite elements method; fiber reinforced polymers; Ansys.

Streszczenie. Celem artykułu jest weryfikacja dokładności modelu Cohesive Zone Model (CZM), zaimplementowanego w programie Ansys, w modelowaniu numerycznym belek żelbetowych wzmacnianych taśmami z polimerów zbrojonych włóknami (FRP).Wzięto pod uwagę jedynie postać II utraty przyczepności, co jest wystarczające w przypadku belek zginanych wzmocnionych taśmą przyklejoną do ich spodu. Wyniki pokazują zadowalającą zgodność użytego modelu z danymi eksperymentalnymi i tym samym potwierdzają użyteczność CZM do rozwiązywania ww. zagadnień.
Słowa kluczowe: konstrukcje betonowe; metoda elementów skończonych; polimery wzmacniane włóknami; Ansys.
