Abstract:
Discusses design considerations for a prestresed concrete bridge in which the girders were assembled from precast blocks groouted after completion of the members. Field experience showed that a reduction in the number of shapes of blocks used was desireable and resulted in lower over-all cost. Breakage of blocks and difficulties of grouting in between blocks were overcome by modification of assembling technique, changes in design and the development of re-usable joint covers. Bid prices on three sucessful jobs indicate that with familiarity with prestressed construction the cost tends to drop.
