Abstract

Saat ini konstruksi bangunan gedung bertingkat banyak didominasi oleh beton karena dianggap memiliki berbagai kelebihan. Namun beton memiliki kekurangan antara lain bentuk yang telah dibuat sulit untuk diubah, lemah terhadap kuat tarik, mempunyai bobot yang berat, dan pelaksanaan pekerjaan yang relatif lama. Dari kelemahan tersebut maka perlu adanya material yang mutunya tidak kalah dengan beton, antara lain baja. Material baja sebagai bahan konstruksi telah digunakan sejak lama mengingat beberapa keunggulannya dibandingkan material yang lain. Struktur baja merupakan salah satu sistem struktur tahan gempa dengan kinerja yang sangat bagus, karena material baja mempunyai sifat daktilitas dan kekuatannya yang sangat tinggi, sehingga sangat cocok digunakan untuk daerah-daerah dengan tingkat sismisitas yang tinggi. Salah satu sistem desain strutktur tahan gempa yaitu sistem rangka dengan pengaku eksentris (Eccentrically Braced Frame/EBF). Untuk mendapatkan perilaku bangunan yang aman saat terjadi gempa, dapat dilakukan pengurangan nilai lendutan dan Periode dengan menambah kekakuan bangunan menggunakan Bresing. Bresing pada bangunan berfungsi sebagai Frame yang dapat menahan terhadap gaya tarik dan tekan. Gedung yang digunakan pada Tugas Akhir ini adalah Gedung RSI UNISMA Malang. Dari hasil perhitungan diperoleh hasil, yaitu tebal pelat beton 12 cm, dimensi balok induk WF 400 x 200 x 12 x 21, balok link WF 400 x 200 x 12 x 12, WF 400 x 200 x 8 x 13 dimensi bresing WF 350 x 175 x 9 x 16, dimensi kolom lantai 1 H 500 x 500 x 19 x 32, lantai 2-3 H 450 x 450 x 12 x 25 , lantai 4-9 H 350 x 350 x 12 x 19 Perencanaan pondasi menggunakan bore pile diameter 400 mm dengan kedalaman 20 m. Harga total bahan struktur alternatif GKB IV UMM sebesar Rp 43,808,798,16 (empat puluh tiga milyar delapan ratus delapan tujuh ratus sembilan puluh delapan ribu Sembilan ratus Sembilan puluh enam belas rupiah).

Currently, the construction of many high-rise buildings is dominated by concrete because it is considered to have various advantages. However, concrete has drawbacks, including the shape that has been made difficult to change, weak to tensile strength, has a heavy weight, and the execution of work is relatively long. From these weaknesses, it is necessary to have a material whose quality is not inferior to concrete, including steel. Steel material as a construction material has been used for a long time considering its several advantages compared to other materials. Steel structure is one of the earthquake resistant structural systems with very good performance, because the steel material has very high ductility and strength properties, so it is very suitable for use in areas with a high level of seismicity. One of the earthquake resistant structural design systems is the eccentrically braced frame (EBF) system. In order to get the behavior of buildings that are safe from earthquakes, what can be done is to reduce the deviation and period values by stiffening the building using braces. Bracing elements in buildings function as rods that resist tensile and compressive forces due to lateral loads. The building used in this Final Project is the RSI UNISMA Malang Building. From the calculation results, the results are that the thickness of the concrete slab is 12 cm, the dimensions of the main beam are WF 400 x 200 x 12 x 21, the link beams WF are 400 x 200 x 12 x 12, WF are 400 x 200 x 8 x 13 the dimensions of the bracing are WF 350 x 175 x 9 x 16, column dimensions for 1st floor 500 x 500 x 19 x 32, floors 2-3 H 450 x 450 x 12 x 25 , floors 4-9 H 350 x 350 x 12 x 19 Foundation planning using bore pile diameter 400 mm with a depth of 20 m. The total price for the alternative structure materials GKB IV UMM is IDR 43,808,798.16 (forty three billion eight hundred eight seven hundred ninety eight thousand nine hundred ninety sixteen rupiah).
