Abstract
Penggunaan bahan beton pada struktur semakin banyak ditemui dalam pembangunan konstruksi bangunan sipil. Hal tersebut dikarenakan beton mempunyai beberapa keunggulan dibandingkan baja, diantaranya adalah beton dapat menahan gaya tekan jauh lebih besar dari baja dan dari segi biaya beton lebih ekonomis. Selain itu beton dapat mudah dibentuk sesuai keinginan dan beton mempunyai sifat tahan terhadap panas atau api. Sehingga penggunaan beton bertulang sebagai bahan struktur bangunan lebih cocok dipilih untuk peningkatan pembangunan. Penggunaan teknologi Base Isolator sebagai peredam gempa dinilai sangat penting bagi konstruksi bangunan gedung karena dapat mengurangi gaya gempa yang diterima oleh struktur.
Pembangunan Gedung Apartemen Grand Dharmahusada Lagoon saat ini menggunakan struktur gedung beton bertulang dan shearwall. Dalam Tugas Akhir ini, gedung tersebut akan dimodifikasi menjadi 42 lantai dan 1 lantai pemeliharaan dengan menggunakan struktur beton bertulang pemikul momen biasa dengan Base Isolator: High Damping Rubber Bearing (HDRB). Perencanaan meliputi: perencanaan struktur sekunder, struktur primer, base isolator dan pondasi.
Tujuan dari Tugas Akhir ini adalah menghasilkan perencanaan struktur gedung dengan menggunakan struktur beton bertulang dengan Base Isolator: HDRB dan memenuhi persyaratan keamanan struktur berdasarkan SNI 1726:2012, SNI 1727:2013, SNI 2847:2013 dan beberapa literatur dan peraturan lainnya. Dengan acuan tersebut direncanakan struktur dapat menerima gaya statis dan dimanis berupa gaya gempa sehingga gedung dapat berfungsi sebagai mana mestinya dan dapat memberikan keamanan dalam penggunaan bedung bertingkat.
Dari analisa dan perhitungan diperoleh hasil bahwa dengan adanya Base Isolator dapat mereduksi gaya geser dasar gempa (V) arah X sebesar 26,27% dan arah Y sebesar 25,93%, serta dapat mereduksi simpangan antar lantai pada arah X sebesar 14,34% dan arah Y sebesar 18,69%. Didapatkan pula dimensi elemen struktur: tebal pelat atap 12 cm, pelat lantai 12 cm, dimensi balok anak terbesar 25/40 cm, dimensi balok induk terbesar 50/80 cm, dimensi kolom terbesar 200/150 cm, dan dimensi base isolator HDRB dengan diameter rubber 110 cm.

The use of concrete materials in structures is increasingly in the construction of civilian construction. This is because concrete has several advantages over steel, including concrete that can withstand compressive forces greater than steel and in cost analysis, concrete building is more economical than steel. In addition, concrete can be easily formed as desired and concrete has the properties of resistance to heat or fire. So that the use of reinforced concrete as building material is more suitable to be chosen for increased development. The use of Base Isolator technology as an earthquake damper is considered very important for building construction because it can reduce the earthquake force received by the structure.
The construction of the Grand Dharmahusada Lagoon Apartment Building currently uses a reinforced concrete building structure and shearwall. In this Final Project, the building will be modified into 42 floors and 1 maintenance floor using ordinary moment resisting frame structures with Base Isolator : High Damping Rubber Bearings (HDRB). Planning includes: planning secondary structures, primary structures, base isolators and foundations.
The purpose of this Final Project is to produce building structure planning using reinforced concrete structures with Base Isolator: HDRB and meet structural safety requirements based on SNI 1726: 2012, SNI 1727: 2013, SNI 2847: 2013 and some other literature and regulations. With the reference planned structures can accept static and dinamic forces in the form of earthquake forces so that the building can function as it should and can provide security in the use of highrise building.
From the analysis and calculation, the results show that with the Base Isolator can reduce the base shear force of the earthquake (V) X direction by 26.27% and Y direction by 25.93%, and can reduce the interstrory drift in the X direction of 14.34% and the direction of Y is 18.69%. The dimensions of structural elements were also obtained : 12 cm thick roof plate, 12 cm floor plate, the largest dimension of the secondary beam 25/40 cm, the largest dimension of the beam 50/80 cm, the largest column dimensions 200/150 cm, and dimension ruber of base isolator HDRB is 110 cm.
