El anejo J of Eurocode EN 1992-2, apartados (102) y (104) proporciona el armado para evitar el deslizamiento de borde bajo carga concentra y los requisitos a respetar en cuanto a distancias de la carga concentrada y el borde más próximo.
Es especialmente importante en apoyos de puentes, en
ménsulas cortas ya que son cargas concentradas cerca de bordes. Cuando dimensionamos
el armado de ménsulas cotas es importante tener en cuenta estas cantidades para evitar el deslizamiento del borde.El anejo J of EN 1992-2 lee lo siguiente: - (102) The distance from the edge of the loaded area to the free edge of the concrete section should not be less than 1/6 of the corresponding dimension of the loaded area measured in the same direction. In no cases should the distance to the free edge be taken as less than 50 mm. - (104) In order to avoid edge sliding, uniformly distributed reinforcement parallel to the loaded face shouldbe provided to the point at which local compressive stresses are dispersed. This point is determined as follows: A line inclined at an angle θ (30°) to the direction of load application is drawn from the edge of the section to intersect with the opposite edge of the loaded surface, as shown in Figure J.107. The reinforcement provided to avoid edge sliding shall be adequately anchored.
