Abstract
Perencanaan Gedung Social Security (SS) Tower pada kondisi existing dirancang dengan menggunakan metode cor di tempat dengan ketinggian mencapai 28 lantai. Dalam tugas akhir ini, gedung tersebut akan dilakukan perancangan dengan menggunakan metode beton pracetak dan memiliki sistem ganda (dual system) dengan kategori desain seismik D. Rangka utama didesain sebagai sistem rangka pemikul momen menengah dan dinding struktur beton khusus. Gedung ini direncanakan dengan ketinggian mencapai 15 lantai. Perencanaan dengan elemen beton pracetak diaplikasikan pada balok dan pelat saja. Metode konvensional juga diterapkan pada elemen kolom, dinding geser, dan sambungan. Sambungan direncanakan menggunakan sambungan basah dengan cor di tempat dan injeksi grouting pada NMB coupler sleeve. Dari hasil analisis yang telah dilakukan diperoleh kesimpulan bahwa rangka utama gedung mampu menahan beban lateral X dan Y yang masing-masing bernilai sebesar 35,10% dan 27,91%, sehingga persyaratan untuk sistem ganda terpenuhi. Perencanaan elemen pracetak didasarkan pada tiga kondisi, yaitu sebelum komposit, saat pengangkatan, dan setelah komposit. Pada elemen plat digunakan tebal plat sebesar 18 cm. Dimensi balok anak terbesar adalah 40 x 55 cm dan dimensi untuk balok induk terbesar adalah 55 x 80 cm. Untuk dimensi kolom terbesar adalah 85 x 85 cm, dan dinding geser dengan ketebalan 40 cm. Dalam perencanaan tugas akhir ini penulis menggunakan aturan berdasarkan SNI 2847:2013, SNI 1726:2012, SNI 1727:2013, PCI Design Handbook, dan juga referensi aturan lainnya. Selanjutnya perencanaan tersebut dituangkan dalam bentuk gambar perencanaan sesuai dengan aturan atau standarisasi yang berlaku.

Planning for the Social Security (SS) Tower Building on the existing condition was designed using the cast method in a place with a height of up to 28 floors. In this final project, the building will be designed using a precast concrete method and has a dual system with a seismic design category D. The main frame is designed as a medium moment bearing frame system and a special concrete structure wall. This building is planned with a height of up to 15 floors. Planning with precast concrete elements is applied only to beams and plates. The conventional method is also applied to column elements, shear walls and joints. The connection is planned to use a wet connection with cast in place and injection grouting on the coupler sleeve.
From the results of the analysis carried out, it can be concluded that the main frame of the building is able to withstand lateral X and Y loads which are worth 35.10% and 27.91% respectively, so the requirements for multiple systems are fulfilled. Preprinted element planning is based on three conditions, namely before the composite, when lifting, and after the composite. Plate thickness of 18 cm is used on the plate element. The dimensions of the largest joist are 40 x 55 cm and the dimensions for the largest beam are 55 x 80 cm. The largest column dimensions are 85 x 85 cm, and the shear wall is 40 cm thick.
In planning this thesis the author uses rules based on SNI 2847: 2013, SNI 1726: 2012, SNI 1727: 2013, PCI Design Handbook, and also other rule references. Furthermore, the planning is outlined in the form of planning drawings in accordance with the applicable rules or standard.
