Abstract :
Sungai Pengalir Bridge is located in Sei Village. Injab, Kel. Terkul was built in 2013 using the RSNI T-02-2005 bridge loading standard. Over time, RSNI T-02-2005 has been updated to SNI 1725:2016. So that in this plan using the loading of SNI 1725:2016 with prestressed concrete. This plan aims to obtain effective dimensions, obtain loading results, bar bending schedule results, and cost budget plans. This bridge planning refers to SNI 1725:2016 regarding loading for bridges, SNI T-12-2004 planning of concrete structures for bridges. Based on the results of the calculation of the structure of the bridge is planned with a length of 42 m and a width of 7.5 m. The quality of the K-250 slab concrete with a thickness of 0.2 m uses negative and positive flexural reinforcement, namely the main reinforcement D16-250 mm and reinforcement for D13-300 mm, for prestressed concrete using a PCI Girder profile with a height of 170 cm, beam spacing of 200 cm and quality of prestressed concrete K-602.41. diaphragm obtained tensile and compressive reinforcement 24D10 mm while shearing reinforcement 8-200 mm. The number of tendons is 4 with 49 strands. From the calculation results, the nominal moment of the prestressed beam is 16108.481 kNm, and the ultimate moment capacity of the prestressed beam is 14497.633 kNm.
