Abstract:
The Lower Tampa Bay bridge in Florida is noteworthy in several respects. The Smile crossing will include approximately 3 1/2 miles of concrete trestle constructed with precast and prestressed concrete beams. The bridge in-cludes 363 prestressed concrete stringer spans, each 48 ft long. The reinforce-ment consists of high strength LeeMcCall bars, the first structure in this country to employ this prestressing system. A test program on full size members was set up prior to beginning construc-tion of the bridge. This also gave the contractor a chance to perfect con-struction procedures, which are outlined in the paper. Test results on a beam aided in establishing an empirical standard of quality for the manufacture of units to be used on the job. A "composite beam" was tested to investigate the action of the composite T-section consisting of beam and deck slab.
