Design anchorage length following EC-2
Explanation

This online tool calculates the anchor length of a bar based on the formulation of the EC-2.

Calculation process
 Geometric characteristics Bar diameter (Φs) (mm): Rebar shape Straight Other than straight Cd value (See figure) (mm): coefficient related to the quality of the bond condition and the position of the bar during concreting (η1) (see figure below-Good/poor conditions): Value: η1 = 1.0 when ‘good’ conditions are obtained; η1 = 0.7 for all other cases and for bars in structural elements built with slip-forms, unless it can be shown that ‘good’ bond conditions exist Coefficient related to the bar diameter (η2): Value: η2 = 1.0 for φ ≤ 32 mm; η2 = (132 - φ)/100 for φ > 32 mm;
 Concrete characteristics Concrete tensile characteristic strength (fctk,0,05) (MPa): Concrete partial factor: (γc) Typical values: Persistent & Transient situation:1.5; Accidental situation:1.2; Long term effects on the tensile strength (α,ct) (MPa):
 Steel characteristics Design stress of the bar (σs) (MPa): Tension or compression: Bar in tension Bar in compresion
 transverse reinforcement along the design anchorage length Not welded transverse reinforcement? No Yes Information: In case of doubt, keep the "No" option, is conservative; Not welded trasversal reinforcement area in the anchor length (mm²): Type of element where the anchored bar is placed: Beam Slab K value (see figure) (mm): Welded transverse reinforcement? No Yes Information: In case of doubt, keep the "No" option, is conservative; The welded transverse reinforcement complies with the following requirement? No Yes
 Transverse pressure along the anchorage length Is there transverse pressure along the anchorage length?: No Yes Information: Compression stresss on the concrete where the rebar is anchored, increasing the contact between the rebar and tbe concrete In case of doubt, keep the "No" option, is conservative; Transverse compression pressure (p) (MPa):
