structural support bar connection should be reasonably rigid to hold until the concrete is poured and subsequently cures once the concrete has cured the connection has no further structural purpose pans 34 are positioned on lips 32 of bars 16 and concrete is poured thereon precast panels 12 are then transported to the site and are arranged on structural beams 14 with ducts 20 of adjacent panels in horizontal alignment and with shear connectors 46 and vertical holes 48 in vertical alignment ducts 20 are then coupled post tensioning tendons 42 are inserted through the continuous ducts 20 concrete or grout is poured in a keyway not shown located between adjacent panels 12 and is permitted to substantially cure upon substantial curing of the concrete tendons 42 are tightened and anchored to end panels 12e via post tensioning anchorage elements 44 then holes 48 are filled with concrete or grout if it is desired to form bridge deck 10 using panels with a cast in place construction a number of skeletal units are formed off site as described above if the length of structural support bars 16 either exceeds 60 0 feet or is curtailed by transportation regulations field splicing of the bars should be considered the duct structural support bar connection.
