Abstract
Pada saat ini penggunaan struktur flat slab pada pembangunan konstruksi sipil banyak digunakan. Pelat datar (Flat Slab) adalah pelat beton pejal dengan tebal merata yang mentransfer beban secara langsung ke kolom pendukung dengan kepala kolom atau drop panel tanpa bantuan balok. Penggunaan struktur Flat Slab memiliki kelebihan yaitu menghemat tinggi ruang gedung, pekerjaan dapat dilakukan lebih cepat dan menghemat biaya penggunaan bekisting. Penggunaan Base Isolator untuk meredam gempa penting bagi konstruksi bangunan gedung karena mengurangi gaya gempa yang akan diterima oleh struktur. Base Isolator memiliki sifat fleksibel terhadap gaya horizontal, dan juga mampu menahan berat bangunan dengan baik. Hal ini terjadi karena kombinasi penggunaan material karet dan pelat baja yang tersusun. Dengan sifat fleksibel ini, pada saat gaya gempa menggeser pondasi, base isolator bekerja dengan melakukan simpangan horizontal bolak-balik sehingga gaya yang diterima ke struktur bangunan hanya sebagian kecil. Gedung Hutama Karya Office Tower Jakarta merupakan gedung perkantoran yang pada awalnya didesain dengan menggunakan struktur beton bertulang konvensional. Dalam Tugas Akhir ini, bangunan ini dimodifikasi menggunakan struktur Flat Slab dan Base Isolator : High Damping Rubber Bearing (HDRB). Pada perhitungan bangunan Gedung Hutama Karya Office Jakarta mengacu pada Tata Cara Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung dan Non Gedung SNI 1726-2012, Beban Minimum Untuk Perancangan Gedung dan Sturktur Lain SNI 1727-2013, Spesifikasi Untuk Bangunan Gedung Baja Struktural SNI 1729-2013, Persyaratan Beton Struktural Untuk Bangunan Gedung SNI 2847-2013, ASCE 2000, ACI 2011. Dalam menganalisa strukturnya ditinjau dengan pengaruh beban gempa dinamis menggunakan program bantu ETABS. Dari analisa dan hasil perencanaan diperoleh hasil yaitu : Tebal pelat tangga dan pelat bordes 15 cm, serta dimensi balok bordes 30/45 cm. Tebal pelat lantai dan pelat atap 22 cm. Dimensi drop panel 1,5m x 1,5m dengan tebal 15 cm. Dimensi kolom lantai terbesar yaitu 1m x 1m. Perencanaan base isolator : high damping rubber bearing digunakan dimensi HH70x6R. Pondasi mengguunakan tiang pancang dengan diameter Ø50 cm pada kedalaman 14 m dengan dimensi poer 2,8m x 2,8m x 1 m dan dimensi balok sloof sebesar 35/50 cm.

At present time, the use of flat slab structures in civil building construction is widely used. Flat Slab is a solid concrete plate that transfers the load directly to the supporting column with a column head or drop panel without the support of beam. The use of Flat Slab structures has some advantages such as having shorter story height, faster construction time and construction cost reduction due to less amount of formwork required. Use of Base Isolators to absorb and damp earthquake is important for building construction because it reduces the earthquake force that will be subjected to the structure. Base Isolator has a flexibility against horizontal force, and is also able to withstand the weight of the building properly. This happens because of the combined usage of high-density rubber and steel plates inside them. With this flexibility characteristic, when earthquake forces shift the foundation, base isolators work by alternating horizontal deviation so that the force transmitted into the building structure is only a small part. Hutama Karya Office Tower Jakarta is a building consisting of 16 floors which was originally designed using conventional reinforced concrete structures. In this Final Project, this building was modified using Flat Slab and Base Isolator structures: High Damping Rubber Bearings (HDRB). The calculation of Hutama Karya Jakarta Office Building refers to the Earthquake Design Procedure for Structural and Non Structural building based on SNI 1726-2012, Minimum Loading Design for Buildings and other structures based on SNI 1727-2013, Specifications for Structural Steel Buildings SNI 1729-2013 , Structural Concrete Requirement for Building based on SNI 2847-2013, ASCE 2000, and ACI 2011. In the structural analysis, the influence of dynamic earthquake loads was calculated using ETABS computer software. Based on the analysis and the design of the building, the following results are obtained : Thickness of the staircase slab and landing slab is 15 cm, and the dimensions of the staircase landing beam is 30/45 cm. Floor slab and roof slab thickness is 22 cm. The dimensions of the drop panels are 1.5m length x 1.5m wide and 15 cm thick. The biggest column dimensions are 1m x 1m. Base isolator design: high damping rubber bearing dimension is HH70x6R. The foundation of the building is spun pile with Ø50 cm diameter at a depth of 14 m with pilecap dimensions of 2.8 m long x 2.8 m wide x1 m thick and the dimensions of the sloof beam are 35/50 cm.
