Abstract

Pemasangan tower Galang-Simangkuk bertujuan untuk meningkatan kualitas pelayanan terhadap pelangganPT.PLN. Tower Galang-Simangkuk berada pada kontur geografis daerah perbukitan, pegunungan, lembah dan jarak yang sangat berjauhan antar subsistem di wilayah Sumatra, maka sistem interkoneksi Sumatra perlu dikembangkan pada tegangan sistem ekstra tinggi atau disebut dengan sistem transmisi 275 KV Sumatra. Terdapat kendala dilapangan yaitu tanah yang berawa, berair, lembah, bukit dan pegunungan. Sehingga dilakukan Perubahan desain dari pondasi dangkal ke pondasi bored pile dibeberapa titik lokasi pekerjaan. Karena terbatasnya cara pengujian dilapangan maka penyelidikan tanah yang digunakan uji sondir/DCPT. Penyelidikan tanah bertujuan mengetahui perlawanan penetrasi konus dan hambatan lekat tanah yang merupakan indikasi dari kekuatan dukung lapisan tanah dengan menggunakan rumus empiris. Tujuan penelitian ini untuk mengetahui daya dukung pondasi bored pile dan stabilitas tower. Dari hasil perhitungan dan pembahasan didapat sebagai berikut: 1). Hasil perhitungan efisiensi kelompok tiang diperoleh sebesar 0,714 yang berarti bahwa kemampuan daya dukung tanah pondasi sebesar 71,4% dari perhitungan Qg, 2). Hasil perhitungan daya dukung tiang group berdasarkan efisiensi pada tower diperoleh sebesar Qg = 484,456 ton, 3). Beban yang dipikul pondasi sebesar 110,13 ton(Diperoleh dari pabrikan), 4). Sehingga beban yang dipikul pondasi bore pile sebesar 484,456 ton dimana nilai lebih besar dari gaya yang bekerja yaitu 110,13 ton. 484,456 ton > 110,13 ton.Maka daya dukung pondasi sanggup menahan beban diatasnya dan aman.

Abstract

A planner is required to be able to design with high usability, efficiency, and aesthetics. Many aspects must be considered when designing a construction, one of which is concrete. The effect of earthquake loads is one of the important things to analyze because the effects on buildings can be harmful to humans. Therefore, a good design is needed in order to reduce the level of accidents and losses caused. In this thesis, the building being reviewed is a 30-floor apartment building which is the newest apartment in the city of Medan. The calculation of the structure refers to SNI 2847-2013 for reinforced concrete designs, SNI 1726-2012 for designs against earthquakes and SNI 1727-2013 for loading on structures. The calculation of the building structure is reviewed for dead loads, live loads and earthquake loads. Calculations carried out include slab, beam, column and foundation elements. The SAP 2000 application was used to help calculate the structural element forces. From the calculation results there were differences with the designs used in the field, this happened because each structural planner used certain calculation rules and procedures in designing the structure. However, the difference between the results of the analysis and the design in the field is not very significant, so we can assume that the beam, column and floor slab designs are safe to use.
