Anchorage of longitudinal reinforcement: the basic anchorage length lb,rqd

Eurocode 2 part 1-1: Design of concrete structures \$(document).ready(function () { var freeExample = \$("#freeExample").length; \$("#mainMenu li#nav-appCate, #mainMenu li#nav-appEC211").addClass("active"); var proUser = false === true || false === true || freeExample !== 0; if (!proUser) { \$('#Input input').keyup(function(){ \$('#AlertSubscribe').modal(); }); \$('#Input select').change(function(){ \$('#AlertSubscribe').modal(); }); }; var tempInput = \$("#tempInput").text(); if (tempInput != "") { \$("#Input").parent("form").deserialize(tempInput); if (proUser) { \$("#acceptBtn").trigger("click"); } }; });  8.4.3 (2)

The basic required anchorage length in a straight bar follows from:

 lb,rqd = (Φ/4)⋅(σsd/fbd) (8.3)

where:

Φ
is the bar diameter
σsd
is the design stress of the bar at the position from where the anchorage is measured from
fbd
is the design value of the ultimate bond stress.

This application calculates the basic anchorage length lb,rqd from your inputs.

Input
mm
MPa

Output
the basic anchorage length lb,rqd
