Good Evening / Morning. Due to a additional load on an existing isolated footing, I’m trying to widen and reinforce it by using the jacketing technic, using two orthogonal beams as per the attachement My question is about new beams reinforcement : 1.Is longitudinal beams reinforcement , by direction , should balance all the new effort from the column , regardless existing reinforcement in the existing footing ? 2. What are disposition for calculating links between old and new concrete? Thanks a LOT.
