Choosing boundary conditions or effective length, regardless of the method of design, would tell the program to assign the right buckling lengths to members. If this is true, can we not use effective lengths to carry out our design acc. to general method in EC3?
Hi, Civil3000! In fact it is not exactly the same input needed - for general method acc 6.3.4 we only need boundary conditions for the out-of-plane behavior (because its only a 4 DOF eigenvalue solver demanded by that method in EC3) so we have chosen to provide two input objects and let the user decide the design method by choosing the corresponding input object.
12:45 when assigning global sway imperfections, why is the height of the shorter tower is selected as the structure's height? Wouldn't it be right if we chose each of the two towers separately and assigned global sway imperfections because they have different heights?
Hi, Civil3000! Yes indeed we could choose the two correct heights but it is on the safe side to only use the shorter length - so we have only chosen the shorter one in order to simplify the input.
Ohayo! Feels good today. Electrifying i find it. I love the feel. Magnificient.
Ciao!
Thank you for this Video its very useful!
