Abstract

Indonesia berada pada jalur cincin api (Ring of Fire) sehingga beban gempa menjadi faktor utama dalam perencanaan bangunan bertingkat tinggi. Salah satu upaya meningkatkan kinerja struktur terhadap gempa adalah penggunaan Fluid Viscous Damper (FVD) yang mampu mereduksi gaya geser dasar, simpangan, dan percepatan struktur. Penelitian ini mengkaji alternatif desain gedung hotel 20 lantai di Surabaya dengan mengganti sistem ganda (SRPMK dengan dinding geser) menjadi Sistem Rangka Pemikul Momen Biasa (SRPMB) yang dilengkapi FVD, serta membandingkan perilaku struktur dan efisiensi biaya kedua sistem melalui analisis Rencana Anggaran Biaya (RAB). Analisis dilakukan melalui empat tahap pemodelan, yaitu sistem ganda dengan dinding geser, SRPMK tanpa dinding geser, SRPMB tanpa FVD, dan SRPMB dengan FVD. Setiap tahap ditinjau melalui kontrol perilaku struktur yang mencakup rasio partisipasi massa, periode fundamental, gaya geser dasar, simpangan antarlantai, P-Delta, dan ketidakberaturan struktur. Selanjutnya dilakukan perhitungan kapasitas elemen struktur, perencanaan breising dan sambungan FVD, penyusunan metode pelaksanaan, serta analisis RAB untuk membandingkan kebutuhan biaya kedua sistem. Hasil penelitian menunjukkan FVD yang digunakan adalah tipe 17200 produksi Taylor Device jenis linear dengan koefisien redaman 20% dan eksponen kecepatan (α) sebesar 1, sebanyak 72 unit berkonfigurasi diagonal pada lantai 1 hingga 14. Penerapan FVD meningkatkan gaya geser dasar dari 16.059,66 kN menjadi 22.987,36 kN, mereduksi periode fundamental 52,40% menjadi 3,224 detik, serta menurunkan simpangan antarlantai 47,88% pada arah X dan 84,59% pada arah Y sehingga memenuhi batas izin. Seluruh komponen sambungan FVD telah dikontrol dan memenuhi persyaratan, dengan metode pelaksanaan yang menggunakan angkur cor ditempat agar penyaluran gaya berlangsung optimal. Dari sisi biaya, struktur alternatif desain mengalami peningkatan sebesar 73,18% dibandingkan struktur eksisting.

Indonesia lies along the Ring of Fire, making seismic loading a primary consideration in the design of high-rise buildings. One approach to improving structural performance against earthquakes is the use of Fluid Viscous Dampers (FVD), which can reduce base shear, displacement, and structural acceleration. This study examines an alternative design for a 20-story hotel building in Surabaya by replacing the dual system Special Moment Resisting Frame (SMRF) with shear walls with an Ordinary Moment Resisting Frame (OMRF) equipped with FVD, and by comparing the structural behavior and cost efficiency of the two systems through a budget cost estimate analysis. The analysis was carried out through four modeling stages, namely the dual system with shear walls, the Special Moment Resisting Frame without shear walls, the Ordinary Moment Resisting Frame without FVD, and the Ordinary Moment Resisting Frame with FVD. Each stage was evaluated through structural behavior checks covering mass participation ratio, fundamental period, base shear, inter-story drift, P-Delta effects, and structural irregularity. Subsequently, the structural element capacity was calculated, the FVD bracing and connections were designed, the construction method was developed, and the RAB analysis was conducted to compare the cost requirements of the two systems. The results show that the FVD used is Type 17200 manufactured by Taylor Device, of the linear type, with a damping coefficient of 20% and a velocity exponent (α) of 1, totaling 72 units in a diagonal configuration installed from the 1st to the 14th floor. The application of FVD increased the base shear from 16,059.66 kN to 22,987.36 kN, reduced the fundamental period by 52.40% to 3.224 seconds, and lowered the inter-story drift by 47.88% in the X direction and 84.59% in the Y direction, thereby satisfying the permissible limits. All FVD connection components were checked and met the requirements, with a construction method employing cast-in-place anchors to ensure optimal force transfer. In terms of cost, the alternative design structure experienced an increase of 73.18% from existing design.
