About this detail

Connection and reinforcement layout for a new thirty-by-fifty-four-inch grade beam adjacent to an existing eighteen-by-fifty-four-inch grade beam. The new beam is reinforced with four number eight top bars, five number eight bottom bars, number five closed hoops spaced at eighteen inches on center, and number five stirrups at eighteen inches on center. The existing grade beam ties into the new beam using number five epoxy dowels spaced at thirty-six inches on center at both the top and bottom surfaces, with surface roughening not required. An existing slab on grade bears on the assembly, requiring selective demolition and replacement referenced from the structural drawings. Additional reinforcement includes number five bars at twelve inches extending eighteen inches into the grade beam, and four number eight top dowels anchored into the existing footing at each end.
