Abstract/Description
-
The feasibility of the use of precast prestressed concrete multi-box beams with transverse post tensioning is examined for a medium span bridge system based on analytical and experimental studies on a 1:2.5 scale model. Constant amplitude fatigue loading was applied on the model at typical locations simulating HS20-44 AASHTO truck loading. The performance of the bridge system was evaluated in terms of deflections, strains in the concrete, wheel load distribution, and behavior of longitudinal...
Show moreThe feasibility of the use of precast prestressed concrete multi-box beams with transverse post tensioning is examined for a medium span bridge system based on analytical and experimental studies on a 1:2.5 scale model. Constant amplitude fatigue loading was applied on the model at typical locations simulating HS20-44 AASHTO truck loading. The performance of the bridge system was evaluated in terms of deflections, strains in the concrete, wheel load distribution, and behavior of longitudinal joints with increasing number of cycles of fatigue loading. A grillage analysis of the bridge system was carried out to predict the elastic behavior and the cracking moments and the results compared with the experimental values.
