Abstract
The Palu 4 Bridge, which is located in the middle of Palu City, is the bridge that serves the busiest traffic in Palu City. After the collapse of this bridge on September 28 2018, the author will make construction modifications to the Palu 4 Bridge. This planning starts with collecting existing data. Then proceed with the selection of the bridge type. The basics of planning refer to SNI 1725; 2016. After that, the initial planning is carried out by determining the main dimensions of the bridge. At the initial planning stage, the calculation of the secondary structure of the bridge was carried out. Load analysis that occurs such as: analysis of self-weight, additional dead load, traffic load, and analysis of the effects of time such as creep and loss of prestress. Then from the results of the analysis carried out stress control that occurs in the structure, calculation of box girder reinforcement, calculation of the strength and stability of the structure against the initial prestressing force, loss of prestressing force and spectrum response. Box girder with a cantilever construction system. The bridge is planned with a length of 249.4 m with a width of 12.4 m. The results of this final project include the use box girder with a width of 12.4 m, a height of 3.5 m, and a length of 3 m per segment, the number of tendons used is 16 pieces, the total strands used 304 pieces, loss of prestressing force of 15.18% and the amount of deflection of the bridge box girder the largest cantilever is 0.195 m. The dimension of bearing pad to be used is 700 x 700 x 177 mm. From the parameters mentioned above, it can be concluded that this bridge is able to withstand the load on the superstructure of the Palu 4 Bridge. Keywords : Box Girder, Cantilever, Stability, Prestressing Force, Bearing Pad
