Hi all,
I am assessing capacity of the signal gantry across railway tracks. This structures is basically a lattice type girder. I am designing it to Eurocode 1991-1-3. The rsult shows some of the members (top and bottom boom and a piece of column ) are failing.
for example, member 419 is failing in cl. 6.2.9.2/3 which is not appliocable when the shear force doesnt exists. in this case shear force exists, even though program does checks it to that clause and fails.
Similarly, for column it is failing in additional checks for cl. 6.2.7 which is not done for other column members!!.
Please let me know if i am doing it right?
I have attached the staad file here.
