PERENCANAAN ULANG STRUKTUR BAWAH GEDUNG PUSAT PENGEMBANGAN IPTEK DAN INOVASI GAMBUT UNIVERSITAS PALANGKA RAYA MENGGUNAKAN PONDASI BORED PILE TIPE FRANKY PILE

The UPR Peat Science and Technology and Innovation Development Center building is an 8-story building built on an area of approximately 30,000 m2, and with a height of 33 m, tall buildings need to be supported with a strong foundation. From the structural calculations above, the largest load that occurs is obtained on Grid E-4 with Pu = 506 tons. Based on soil data that the depth of the Franky Pile Type bore pile foundation is planned to be 18 m with a bore pile dimension of 60 cm and a pile tip dimension of 80 cm, the bearing capacity is obtained at 168.94 tons / pile and per group on Grid E-4 with an efficiency of 71.71%, the bearing capacity is obtained at 512.7 tons > Pu = 506 tons. And the results of pile cap planning on the drill pile used D22-100 type 1 foundation pile cap reinforcement for x and y direction reinforcement, D10-200 shear reinforcement is used, 1D19-150 shrinkage reinforcement is used for foundation type 2 and 2D16-200 for foundation type 1. With a diameter of 4.00 m x 4.00 m x 1.00 m for foundation type 1 pile cap. While the reinforcement of drill piles for the 60 cm drill pile dimension and 80 cm pile tip dimension uses 10D19 mm longitudinal reinforcement and D13-100 mm spiral reinforcement. And from the settlement calculation results, the largest settlement is 3.319 cm in Grid E-4.
