The excessive deflection of large-span cantilever cast prestressed concrete (LCCPC) box girders has always been a complex problem to be solved in bridge engineering. To analyze the effect shear deformation at segmental joints on LCCPC girders, comparison tests were carried out three (PC) I-girders with and PC I-girder without joints, finite element simulation method was proposed based tests. Su...

This paper describes an experimental program undertaken at the University of Manitoba to study the serviceability of concrete beams prestressed by carbon fibre reinforced plastic (CFRP) rods. The experimental program consisted of eight concrete beams prestressed by CFRP rods and two concrete beams prestressed by conventional steel strands. The beams were tested using two static concentrated loa...

The definition of sustainability includes three fundamental pillars: economic, environmental, and social. Studies the economic impact on civil engineering infrastructures have been focused cost reduction. It is not necessarily in line with due to lack other factors. Moreover, social pillar assessment has weakly developed compared environmental ones. essential focus evaluate clear indicators tha...

Page 1 UT students placed very well in the 2012 Big Beam Contest, with one team earning first place in the Zone 2 and national competitions. The Big Beam Contest is organized by the Precast/ Prestressed Concrete Institute's (PCI) Student Education Committee, and sponsored by Sika Corp. The contest consists of a zone competition and a national competition. First place winners of each zone, along...

The study object is a prototype of composite bridge prestressed concrete beam with length 42.0 m for road desks perception impact from motor vehicles in the form A14, NK-120 and NK-180 loads.

Abstract For a 60 m prestressed concrete box girder bridge using structural analysis software as ANSYS and MIDAS/civil, combined with several creep prediction models, reasonable model has been obtained. Considering the influence of tendon relaxation on shrinkage concrete, refined finite element is established for numerical compared experimental data. The comparison results show that calculated ...

The durability of precast structures often depends on quality execution the connections between structural elements. Essential also is their design and proper exploitation. This paper focuses magnitude damages as well repair methods used for a slab, which consists prestressed double T slab elements supported inverted girders. It was found that during execution, girders were forced to fit dowel ...
