A case study is made on a three-span PSC box girder bridge in China. The system configuration, sensor layout, and data communications, and so forth, are presented. Bridge performance undergoes time-varying changes when exposed to aggressive environments. While much work has been done on bridge reliability under corrosion, little is known about the effects of creep and shrinkage on the reliability of concrete bridges. This paper presents a method of probabilistic analysis and a sensitivity analysis of the effects of creep and shrinkage in prestressed concrete (PSC) box girder bridges.

psc box girder 2Prestressed concrete (PSC) box-girder bridges are extensively used in highway and railway construction. Excessive long-term deflection and unexpected cracks however are often observed. This paper describes a method of statistical analysis and a sensitivity analysis of the effects of creep and shrinkage in prestressed concrete (PSC) box girder bridges. Full-scale box girder members were fabricated and tested.

Bridges are the key elements in any road network Use of box girder is gaining popularity in bridge engineering fraternity because of its better stability, serviceability, economy, aesthetic appearance and structural efficiency.
