Hello! Can it be negative to oversize the reinforcement in a beam that is supposed to be under subfloor beams, for example, 7 pieces of 16mm with distances of 50mm in a row below and 1 similar row 60mm above the first row and finally another similar row 60mm above the second, i.e., a total of 21 pieces of 16mm laying reinforcements (in 3 rows) in a beam that is 500mm wide x 250mm high x 5200mm long. It will stand on 2 points (side walls of lecablock) one 350mm and the other 250mm wide. NOTE! The floor beams that will be on top of them are 11 glued laminated beams, 90 x 270 x 11000mm. On the second floor, there will be a bathroom, laundry room, and kitchen.
Best regards/Anette
