Abstract

Preflex beams are prestressed by the predeflection technique, which enables the use of concrete-encased high strength steel beams where deflection or cracking of concrete, or both, would otherwise be excessive. This study presents the analysis of the two span preflex composite girder bridges with Load and Resistance Factor Design(LRFD), which is most widely used design nile in the advanced states. The results show that the comparison of LRR with Allowable Stress Design(ASD) according to span length.
