5.2.2(7)a<br />
Path 1a specifies the so called Equivalent Column Method. In step 1b and 2a “l_b may be taken<br />
equal to L”. This is according to EC-EN so the user does not have to calculate the buckling factor =1.<br />
In further analysis a buckling factor smaller than 1 may be justified.<br />
