Hi,
thank You for Your answers. SUDIP this second construction is just for a visualization of crane beam just to check possible high and space between beams.
I made some changes to my model :
1) i changed beta angles on my main columns close to the gate (and on the end wall from left) and i changed property from HEB200 to HEB240.
2) i made corrections with roof plates, like You mentioned Sudip. Before I didn't know if the "idea" of this connection is good and that is why i connected those plates only with nodes where i have main columns. Now i connected roof plates not only to columns but to top nodes of the truss. Are You suggesting to connect roof plates to all my nodes in the truss? This will create many small plates on the roof. Is this necessary ?
3) I added few releases between elements and i added extra stiffeners.
Now i have displ in X direction equal 21,5 mm in node 378 which is much better but still is this not to much ? I know that i can add column with property HEB300 and few more stiffeners but is this the point ?
And now when displ in X is smaller, the biggest displ which i have is in Y direction and it is equal 56 mm in node 251. I am sorry that i am making so much trouble (where maybe there is not) but i am just trying to understand analysis and check if with my model is everything ok.
Again i am attaching model with corrections.
I coudn't add attachment so i added link from speedyshare
