Abstract
Indonesia merupakan negara dengan resiko gempa yang cukup tinggi, baik itu gempa vulkanik maupun gempa tektonik karena terletak pada tiga lempeng tektonik yang aktif yaitu lempeng Indo-Australia, Eurasia dan Pasifik. Maka dari itu, bangunan gedung di Indonesia harus direncanakan untuk tahan terhadap gempa. Seperti halnya perencanaan Gedung Hotel di Malang, gedung ini memiliki 16 lantai yang akan dirancang menggunakan metode base isolation Lead Rubber Bearing dengan Sistem Rangka Pemikul Momen Biasa (SRPMB). Hal ini bertujuan untuk mengetahui respon bangunan terhadap beban gempa yang lebih besar. Penggunaan LRB dapat mereduksi beban gempa pada bangunan, sehingga cocok digunakan pada bangunan yang berada di daerah rawan gempa. Jenis sistem isolasi ini memiliki kapasitas redaman yang tinggi, fleksibel pada arah horizontal, serta memiliki kapasitas kekakuan yang tinggi pada arah vertikal.
Perencanaan dimulai dengan pengumpulan data eksisting dan membuat dua permodelan sesuai dengan dimensi eksisting. Permodelan yang pertama yaitu struktur SRPMB yang dianalisa dengan pembebanan gempa respon spektrum. Perrmodelan yang kedua yaitu struktur dengan Base Isolation yang dianalisa dengan pembebanan gempa respon spektrum komposit. Dikarenakan tujuan dari proyek akhir ini untuk mengetahui pengaruh LRB terhadap beban gempa yang tinggi (SRPMB nilai R=3), maka pada kedua permodelan dilakukan perbandingan output gaya dalam untuk mengetahui reduksi yang terjadi. Tahap selanjutnya melakukan perhitungan struktur atas dan struktur bawah yang akan dijelaskan pada penggambaran teknik.
Proyek akhir ini mendapatkan hasil bahwa dengan penggunaan Lead Rubber Bearing (LRB) dapat mereduksi gaya geser dasar bangunan arah X sebesar 49,73% dan arah Y sebesar 47,53%. Berdasarkan hasil analisa rasio gaya dalam, terdapat reduksi gaya aksial sebesar 29,05%, gaya geser sebesar 18,72%, gaya momen sebesar 14,61%, dan torsi sebesar 8,06% pada elemen struktur utama. Dan total kebutuhan biaya yang dibutuhkan untuk pemasangan base isolator Lead Rubber Bearing yaitu sebesar Rp 3,275,036,000.
===================================================================================================
Indonesia is a country with a fairly high earthquake risk, both volcanic earthquakes and tectonic earthquakes because it is located on three active tectonic plates, namely the Indo-Australian, Eurasian and Pacific plates. Therefore, buildings in Indonesia are required to withstand earthquakes. Similar to the planning of the Hotel Building in Malang, this building has 16 floors which will be designed using the Lead Rubber Bearing base isolation method with the Ordinary Moment Resistant Frame System (SRPMB). It aims to determine the response of the building to a larger earthquake load. The use of LRB can reduce earthquake loads on buildings, making it suitable for use in buildings located in earthquake-prone areas. This type of insulation system has a high damping capacity, is flexible in the horizontal direction, and has a high rigidity capacity in the vertical direction.
Planning begins with collecting existing data and making two models according to the existing dimensions. The first model is the SRPMB structure which is analyzed by loading the earthquake response spectrum. The second model is a structure with a Base Isolation which is analyzed by earthquake loading with a composite response spectrum. Due to the purpose of this final project to determine the effect of LRB on high earthquake loads (SRPMB value R = 3), then in both models a comparison of internal force output was carried out to determine the reduction that occurred. The next stage is to calculate the upper structure and lower structure which will be explained in the engineering drawing.
This final project results that the use of Lead Rubber Bearing (LRB) can reduce the basic shear force of the building in the X direction by 49,73% and in the Y direction by 47,53%. Based on the results of the internal force ratio analysis, there is a reduction in the axial force of 29,05%, the shear force of 18,72%, the moment force of 14,61%, and the torsion of 8,06% on the main structural elements. And the total cost required for the installation of the Lead Rubber Bearing base insulator is Rp. 3,275,036,000.
