Abstract
Pertambahan penduduk merupakan suatu hal yang tidak dapat dihindari. Dengan kebutuhan tingkat hunian dan keterbatasan lahan, menjadi alas an utama dibangun High Rise Building. Gedung Hotel Rich Palace Surabaya atau yang sekarang berganti nama menjadi Golden Tulip Legacy Surabaya adalah salah satu High Rise Building 24 Lantai dengan jarak rata rata antar kolom 8 meter dan berada di wilayah yang rawan gempa. Pada tugas akhir ini, gedung Hotel Rich Palace Surabaya akan direncanakan ulang dengan modifikasi penggunaan struktur komposit dan rangka pengaku eksentris bertipe X dua lantai. Material komposit dipilih karena memiliki kestabilan rangka yang lebih baik daripada material baja/beton secara individual.
Sistem Rangka Pengaku Eksentris (EBF) digunakan karena memiliki tingkat daktilitas dan kekakuan yang baik daripada MRF dan CBF yang cocok digunakan pada wilayah dengan kerawanan gempa yang cukup tinggi. Sistem Struktur EBF berfungsi sebagai penahan gaya lateral yang bekerja pada gedung sehingga dapat mengurangi deformasi Horizontal, mengurangi simpangan yang terjadi, dan menjaga kestabilan gedung saat terjadi gempa. Tipe X Dua Lantai dipilih karena memiliki bentuk yang simetris dan letak link yang tidak langsung terhubung oleh kolom.
Perancangan Struktur didasarkan pada standar perencanaan ketahanan gempa untuk struktur bangunan gedung SNI 1726:2019, tata cara perencanaan struktur baja SNI 1729:2015 & AISC 341-10, tata cara perencanaan struktur beton SNI 2847:2019, dan perencanaan beban minimum pembebanan dengan SNI 1727:2013 & PPIUG 1983. Analisa struktur ditinjau dengan menggunakan program bantu ETABS 2016.
Dari analisa, dan perhitungan yang telah dilakukan didapatkan hasil perencanaan tebal plat lantai adalah 9 cm dan 12 cm dengan material beton, dimensi balok induk lantai menggunakan WF 700.300.13.20, WF 600.300.12.17, dan WF 500.200.11.19 dan atap menggunakan WF 500.200.11.19. Dimensi Kolom menggunakan CFT (Concrete Filled Tube) 700.700.25, CFT 600.600.22, dan CFT 500.500.16. Struktur diperkaku dengan EBF dengan panjang link 100 cm (Short Link), dan bracing berdimensi WF 300.300.15.15, pada lantai Ground Floor digunakan material beton fc’30 MPa dengan Kolom 1100 x 1100 dan 800 x 800, Balok Induk 450 x 650, Balok Anak 400 x 600, dinding basement dengan tebal 25 cm, dan plat basement dengan tebal 25 cm. Dimensi Sloof digunakan 500 x 800 mm. Pondasi direncanakan dengan menggunakan spun pile D80 dan D50 dengan panjang tiang mencapai 22,8 m atau kedalaman 26 m.
=====================================================================================================
Population Growth is essential thing that cannot be avoided. The needs for occupancy rates and limited land, is the main reason why High Rise Building is constructed. Rich Palace Surabaya Hotel of nowadays known as Golden Tulip Legacy Surabaya is one of the 24-story high rise building with an average distance between column of 8 meters, and the structure located in an earthquake zone. In this final project, the Rich Palace Hotel will be re-planned with the modification of the use of Composite Structures and Eccentrically Braced Frame (EBF) Two Story X Type. The composite material was chosen because it has better frame stability than steel/concrete materials individually.
Eccentrically Braced Frames (EBF) system is used because it has good level of ductility and rigidity compared to MRF and CBF, and suitable to be used in high earthquake zone. EBF system serves as a buffer for lateral forces act on the building so the system can reduce horizontal deformation, reduce deviations, and maintain the stability of the building during an earthquake. Two Story X type was chosen because it has a symmetrical shape, and the location of links that are directly not connected by the column.
Structural Design is based on earthquake resistance planning standards for building SNI 1726:2019, procedures for planning steel SNI 1729:2015 & AISC 341-10, procedures for planning concrete structures SNI 2847:2019, and procedures for loads with SNI 1727:2013 and PPIUG 1983. The structural analysis was analyzed by using ETABS 2016.
From the analysis and calculation that have done, it found that the design result of the floor slab is 9 cm and 12 cm with concrete material, the dimensions of the floor main beam using WF 700.300.13.20, WF 600.300.12.17, and WF 500.200.11.19 and the roof uses WF 500.200.11.19. Column dimension using CFT (Concrete Filled Tube) 700.700.25, CFT 600.600.22, and CFT 500.500.16. The structural rigidity using EBF with link length of 100 cm (short link), brace dimensions WF 300.300.15.15, on the Ground Floor using concrete fc’ 30 MPa with columns dimension 1100 x 1100 and 800 x 800, main beam 450 x 650, secondary beam 400 x 600, basement wall 25 cm thick, and basement plate 25 cm thick. The sloof dimension is 500 x 800 mm. The foundation design using concrete spun pile D80 and D50 with pile length 22,8 m or a depth of 26 m.
