The Kisaran – Indrapura Toll Road is a toll road part of the Trans Sumatra toll road which connects Indrapura with Kisaran in North Sumatra province. During the work on the Kisaran – Indrapura toll road there is also bridge construction work which must be calculated correctly in accordance with applicable regulations. Where the results of the calculation affect the reinforcement that will be used in the bridge superstructure to be able to carry the working loads, then the calculation of the loading and reinforcing will be carried out in accordance with the latest regulations in force using the loading regulations for bridges (SNI 1725:2016), Practical Guide Bridge Planning (SE/Db/2021), Bridge Management System (BMS), AASHTO 1992 and will also evaluate the calculation of the bridge superstructure using PCI Post-Tension girders. From the results of loading and reinforcement calculations based on (SNI 1725:2016), it was found that the floor plate load due to its own weight was 6,250 kN/m', additional dead load = 8,849 kN/m', truck load = 146.25 kN, wind load = 7,887 kN , load temperature difference
= 12.5°C. For the load on the bridge girder due to the self-weight of the prestressed beam = 45.194 kN/m', additional dead load = 1.03 kN/m', lane load = 16.329 kN/m', brake force = 35.714 kN/m', wind load = 7,887 kN/m', earthquake load = 4,620 kN/m'. For the results of the floor plate reinforcement calculations, the floor plate reinforcement for positive bending reinforcement is D16-150 mm and support (negative) bending reinforcement is D13-200 mm. For the reinforcement of girders and prestressed beams with a diameter of 13 mm, a distance of 100 mm, all the reinforcement analyzed is in accordance with the reinforcement of floor plates and girders that have been carried out on the bridge.
