Hello, 6-storey structure and piled raft are defined and ground bearing coefficient Zero is taken for the raft. The whole system carries piles, but the elements take too much design effects because the number of piles is insufficient in your structure. 1.) You can abandon the pile. Soil safety stress is 14 tf/m2. See if there is any need. or 2.) You can increase the number of piles. beam normal forces decrease when pile is defined or only raft foundation is defined Nmax warning disappears Also we recommend updating to 8.504."49emrah49":15smj98y" said:Nmax error is not resolved in sloping beams in reinforced concrete roof design, can you help
