- ABSTRACT Prestressed concrete system are commonly used in bridge construction because it gives stresses to reduce or eliminate the tensile stress. One of the methods to analyze prestressed concrete used in this study is the load balance method by T. Y. Lin that states the prestressed can balance external loads on the bridge span structure. The method is suitable for bridges since its construction is more complex than other building structures. The result of Sengkaling prestressed bridge is that it applied post-tensioned method using PCI profile girder as its main structure. The prestressed cable for this bridge is the uncoated 7 wire super strands ASTM 416 Grade 270 of low relaxation strand. The prestressed girder is considered as a full prestressed. The principles of the PCI girder refers to the Concrete Structure Planning for Bridge (SNI T-12-2004), the bridge load of (SNI T-02-2005). The dimension of girder is 1.70 meter long, 0.80 meter top width, and 0.70 meter bottom width, with gider span of 28.00 meter. The prestressed girder is using 80 strand (prestress force = 10281,6 kN), type VSL with strand diameter Ø98.72 (12,7 inch) divided to 4 tendons, each of which has 20 strands (prestress force = 2570,41 kN).
