(2020-04-08)When constructing prestressed concrete girder bridge structures, the high initial pretensioned force at the bottom of the girder causes it to camber upwards. This hogging of girders may be reduced slightly after casting ...
-
(2013-08-12)Traditionally, prestressed concrete girder bridges are limited to 150 ft span lengths in Texas due to restrictions on handling and transportation. An effective way of increasing span lengths of precast, prestressed concrete ...
