Sound barrier foundation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I am designing a sound barrier, which consists of precast concrete panels spanning horizontally between steel columns @ 12'-6". The columns are founded on 30" diam x 12'-0" deep cast-in-place caissons. Of course the vertical load is almost zero, but there is a moment and a horizontal force applied at top of the footing. The question is about the minimum reinforcement allowed for this type of foundation. Is the usual Rho = 0.01 also applicable in this case, or is it possible to use a lower value considering the size of the caissons? Thanks in advance.
