What type of piles are you using? What is your soil? Can you use longer piles or larger piles and use 2 per column load with the foundation beam acting as a 'pile cap'?
Are the piles friction type or end bearing? Can you use expanded base piles? How thick is your pilecap? Do you have to worry about 'mass concrete' and thermocouples?
Lots of questions...
Can somebody share an example of these calculation? Its quite simple, the details are in EC 1995-1-1 Annex B. I am trying to make a simple spreadsheet in excel for checking mechanically connected beams. Looks like I have a mistake somewhere because my results looks strange but I cant find it.. Probably there is some example in some literature or paper, but I steel didnt find it. Thanks in advice.
