SEGMENTAL Box GIRDER : EFFECT OF SPATIAL RANDOM VARIABILITY OF MATERIAL ON DEFLECTIONS
In a preceding paper (Bazant and Kim 1989), a method of probabilistic prediction of the confidence limits on long-time deflections and intemal forces of prestressed concrete segmental box-girder bridges was developed. The sampling method was used. and predictions were improved by Bayesian updating on the basis of short-time measurements. The entire analysis, including its Baye~ian aspect, was m...

15 صفحه اولExplanation of Excessive Long-Time Deflections of Collapsed Record-Span Box Girder Bridge in Palau
Explanation of the excessive deflections of the Koror-Babeldaob (KB) Bridge in Palau is presented. This bridge was built in 1977 by the cantilever method and collapsed 3 months after remedial prestressing in 1996. It was a segmental prestressed concrete girder having the worldrecord span of 241 m (790 ft.) and maximum girder depth of 14.17 m (46.5 ft). The final mid-span deflection was in desig...
