The following equation is the effective length calculation in Eurocode 2 (page 66) for concrete columns.
In that equation, the "k" is defined as follows,
However, in almost all the calculations (in the books, videos etc) have eliminated "θ/M" and "E" from the above and only considered "I/l". (As shown below). Removal of "E" is most probably due to the reason that column and beam both having same stiffness.
My question is,
1. Why they have removed "θ/M" (the rotation for the bending moment)? the rotation (θ) could be different for both column than the beam, so isn't it unsafe to remove it from the equation?. What is the reason for removal of "θ/M" from the equation?
