For concrete elements of > 30 cm thick
At a height of less than 30 cm, RecoMax does not require additional reinforcements. Supports should be used for heights above 30 cm.
RecoMax must be stiffened up to a height of 90 cm by welding a reinforcing mesh. Above 90 cm, additional stays made of rebars should be used.
|Coefficient of friction
μ - the friction coefficient,
βct - the roughness,
b - the construction joint width,
fck - the concrete strength,
as - the steel cross-section,
fyd - the steel strength,
VEd - the force acting in the joint,
η1 - the correction coefficient,
σNd - the normal perpendicular tension in the joint,
α - the reinforcement angle in the joint,
fcd - the concrete strength taking into account the safety factor.
