Up-to-date assurance of bridge layout and analysis? revised to mirror the 5th version of the AASHTO LRFD specifications

Design of street Bridges, 3rd Edition bargains distinct assurance of engineering fundamentals for the layout of brief- and medium-span bridges. Revised to comply with the most recent 5th variation of the yank organization of kingdom street and Transportation officers (AASHTO) LRFD Bridge layout standards, it's an exceptional engineering source for either pros and scholars. This up-to-date variation has been reorganized all through, spreading the cloth into twenty shorter, extra centred chapters that make details even more uncomplicated to discover and navigate. It additionally gains:

  • Expanded assurance of computing device modeling, calibration of carrier restrict states, inflexible process procedure research, and urban shear
  • Information on key bridge kinds, choice ideas, and aesthetic issues
  • Dozens of labored difficulties that permit suggestions to be utilized to real-world difficulties and layout specifications
  • A new colour insert of bridge images, together with examples of historic and aesthetic significance
  • New assurance of the "green" facets of recycled steel
  • Selected references for extra study

Example text

The reinforced concrete piers had two columns directly under the two girders and a tie beam near the top (Fig. 10). A spread footing on dense glacial deposits supported each pier. Piers 2 and 3 were located in the main channel of Schoharie Creek and were to be protected by riprap. Only the abutments were supported on piles. Unfortunately, in the early 1950s when this bridge was being designed, no reliable method was available to predict scour depth. The bridge was opened to traffic on October 26, 1954, and on October 16, 1955, the Schoharie Creek experienced its flood of record (1900–1987) of 76,500 cfs (2170 m3 /s).

These inspections of the bridge were only of the above-water elements and were usually conducted by maintenance personnel, not by engineers. At no time since its completion had the bridge received an underwater inspection of its foundation. Three spans of the Schoharie Creek Bridge on I-90 near Amsterdam, New York, fell 80 ft (24 m) into a rain-swollen creek on April 5, 1987, when two of its piers collapsed. Four automobiles and one tractor-semitrailer plunged into the creek. Ten people died (NTSB, 1988).

Of these three wire cable suspension bridges from the nineteenth century, the last two are still in service and are carrying highway traffic. However, there is one other long-span wire cable suspension bridge from this era that is noteworthy and still carrying traffic: the Wheeling Suspension Bridge completed in 1849 with a clear span of 1010 ft (308 m) (Fig. 11). Fig. 11 Wheeling Suspension Bridge. ) BRIDGE ENGINEERING IN THE UNITED STATES The Wheeling Suspension Bridge over the easterly channel of the Ohio River was designed and built by Charles Ellet who won a competition with John Roebling; that is, he was the low bidder.
