Abstract

Pada saat ini, penggunaan struktur komposit baja-beton dalam pembangunan konstruksi sipil sangatlah banyak dilakukan. Komponen struktur komposit ini dapat menahan beban sekitar 33% sampai 50% lebih besar daripada beban yang dapat dipikul oleh balok baja saja tanpa adanya perilaku komposit. Selain itu, struktur komposit baja-beton juga memiliki berbagai kelebihan, yang diantaranya adalah penghematan berat profil baja, pengurangan penampang baja, meningkatkan kekakuan pelat lantai, meningkatkan kapisatas pemikul beban dan dapat menambah panjang bentang layan. Penggunaan teknologi Base Isolator sebagai peredam gempa juga dinilai sangat penting bagi konstruksi bangunan gedung karena mengurangi gaya gempa yang diterima oleh struktur. Base isolator mempunyai sifat yang fleksibel terhadap gaya horisontal, tapi mampu menahan berat bangunan dengan baik. Hal itu dikarenakan kombinasi antara material karet dan pelat baja yang tersusun. Dengan sifat fleksibel tersebut, saat gaya gempa menggeser pondasi, base isolator melakukan simpangan horisontal bolak- balik dari tanah sehingga gaya tersebut hanya sebagian kecil yang diterima ke struktur bangunan. Apartemen One East Residence Surabaya pada kondisi sebenarnya dibangun dengan menggunakan struktur beton bertulang biasa dan memiliki 33 lantai dan 1 basement. Dalam Tugas Akhir ini, gedung tersebut akan dimodifikasi dengan menggunakan struktur komposit baja-beton dan Base Isolator : High Damping Rubber Bearing (HDRB). Perencanaan yang dilakukan meliputi perencanaan struktur sekunder, struktur primer, base isolator, sambungan dan pondasi. Berdasarkan perhitungan dan analisa struktur didapatkan hasil, yaitu : tebal pelat atap 9 cm, pelat lantai 9 cm, dimensi balok anak terbesar WF 450 x 300 x 11 x 18, dimensi balok induk terbesar WF 800 x 300 x 14 x 26, dimensi kolom terbesar HSS 700 x 700 x 28 x 28 berintikan beton, dimensi base isolator eksterior 900 mm, dimensi base isolator interior 1100 mm, pondasi menggunakan bored pile diameter 80 cm dengan kedalaman 30m, dimensi pedestal terbesar 1500 mm, dimensi pilecap terbesar 960 x 640 x 110 cm dan dimensi sloof 450 x 600 mm. Perencanaan tersebut telah memenuhi persyaratan keamanan struktur berdasarkan SNI 1727:2013, SNI 1726:2012, SNI 1729:2015 dan SNI 2847:2013. Dengan acuan peraturan tersebut diharapkan gedung dapat berfungsi sesuai dengan desain yang direncanakan. ======================================================================================================================== Nowdays, the composite structure is often used in the construction building. The composite structure can support load from 33%-50% which is bigger than the supported steel beam load without the composite behavior. Beside that, the composite structure also offer many other advantages, such as : minimizing steel beam wight, increasing floor plate stiffness, increasing the supported load capacity as well as extending the length of service. The use of base isolation technology as a seismic damper to reduce the earthquake force is very important for construction building. This is because the base isolation technology minimize the earthquake force impact in the building structure . This technology is totally flexible for horizontal force , but also it is able to support the wight of the structure overall. This is possible only, because of rubber material combination with composite plate steel. Through out the flexibility characteristic, the earthquake force shifting up the foundation and the base isolation performs a horizontal cyclic from the ground so that the building receives the lowest earthquake impact force. Currently, the one east residential apartment surabaya has 33 floor and 1 basement made by concrete reinforcement. Thus, in this final project the building will be modified using the composite structure and base isolation : high damping rubber bearing. This design includes secondary and primary structure, base isolation, joints and foundations. Based on this structural analysis, the plate thickness for the roof and building floors is 9 cm. The maximum dimensions of secondary beam is WF 450 x 300 x 11 x 18, while maximum dimensions of primary beam is WF 800 x 300 x 14 x 26. Furthermore, in the column analysis where discovered the maximum dimensions of column is HSS 700 x 700 x 28 x 28 concrete filled tube, the dimensions of exterior base isolation is 900 cm and interior is 110 cm, the pedestal column dimension is 1500 mm. In addition, for the foundations using bored pile with depth 30 m, the maximum pilecaps dimension is 960 x 640 x 110 cm and the sloof is 450 x 600 mm. This design has met the security requirements of the structure based on SNI 1727:2013, SNI 1726:2012, SNI 1729:2015 and SNI 2847:2013. Based on that it is expected that the build can be functional accordace with the planned design.
