Abstract

Perencanaan bangunan tahan gempa mensyaratkan bangunan agar memiliki daktilitas tinggi. Bangunan yang sedang mengalami gaya gempa akan bergerak searah vertical maupun horizontal. Pergerakan bangunan ke arah horizontal mengakibatkan perubahan gaya gravitasi pada struktur dan akan mengalami keruntuhan di bagian terlemah pada struktur. pall friction damper menjadi salah satu alternatif untuk meningkatkan kekuatan lateral struktur. Distribusi slip load pada PFD yang merata memungkinkan reduksi simpangan lantai dan drift antar lantai lebih efektif dibanding peredam geser lainnya
Bangunan eksisting yang digunakan ialah Gedung Tower B2 Apartemen Mahata Serpong Tangerang terdiri dari 34 lantai dengan ketinggian 109,5 m. Gedung tersebut dibangun dengan menggunakan SRPMK dengan Shearwall dan menggunakan material beton bertulang. Struktur bangunan akan dimodelkan ulang menggunakan peredam pasif PFD yang mengacu pada SNI 2847-2019 dan sistem struktur diubah menjadi SRPMB yang mengacu pada SNI 2847-2019. Terdapat 4 tahapan analisa pada pengerjaan proyek akhir ini. Tahapan pertama adalah permodelan kondisi eksisting, lalu pada tahapan kedua dengan menghilangkan Shearwall. Pada tahapan ketiga permodelan struktur SRPMK dengan pall friction damper, lalu di tahapan keempat mengubah sistem struktur SRPMK dengan Pall Friction Damper menjadi SRPMB dengan pall friction damper. Kebutuhan kapasitas pall friction damper didapatkan dari perhitungan batas bawah slip load PFD dan dimodelkan secara trial-eror sampai sistem struktur memenuhi kontrol dinamis struktur sesuai SNI 1726-2019.
Pall friction damper menggunakan friction damper berkapasitas 450 kN milik QuakeTek. Inc berjumlah 233 buah. Pall friction damper dipasang dengan menggunakan breising wide flange (WF) dan pemasangan menggunakan sambungan gusset plate. Hasil analisa parameter, alternatif desain Gedung Tower B2 Apartemen Mahata Serpong Tangerang mengalami penurunan pada parameter yang ditinjau yaitu gaya geser dasar, periode fundamental, dan simpangan antar lantai. Hasil perhitungan yang sudah dikontrol struktur dan kontrol penulangan selanjutnya akan dijelaskan pada penggambaran teknik.
=====================================================================================================
The design of earthquake-resistant buildings requires buildings to have high ductility. Buidings that are experiencing an earthquake will move in a vertical or horizontal direction. The movement of the building in a horizontal direction causes a change in the gravitational forces on the structure and will collapse at the weakest part of the structure. Pall friction damper is an alternative to increase the lateral strength of the structure. The even distribution of slip load on the PFD enables the reduction of floor displacement and drift between floors more effectively than other dampers.
The existing building is used the Tower B2, Mahata Serpong Apartment, Tangerang, consisting of 43 floors with a height of 109,5 m. The building was built using SRPMK with Shear wall and using reinforced concrete material. The building structure will be remodeled using pall friction damper as passive dampers which refers to SNI 2847-2019 and the structural system is changed to SRPMB which refers to SNI 2847-2019 and SNI 1726-2019. There are 4 stages of analysis in the work of this final project. The first stage is modelling the existing condition, the in the second stage by eliminating shear wall. In the third stage of modelling the SRPMK with pall friction dampers, the in the fourth stage changing the SRPMK structure system with pall friction dampers to SRPMB with pall friction damper. The pall friction dampers capacity requirement is obtained from the calculation of the lower limit of the PFD slip load and is modelled on a trial-error basis until the structural system fulfils the dynamic control of the structure according SNI 1726-2019.
Pall friction dampers use Quaketek’s 450 kN friction dampers totaling 233 pieces. Pall friction dampers are installed using wide flange (WF) braces and mounted using gusset plates connection. The results of the parameter analysis, the alternative design of the Tower B2, Mahata Serpong Apartment, Tangerang, experienced a decrease in the parameters reviewed, namely base shear force, fundamental period, and displacement between stories. The results of calculations that hace been controlled by the structure and control of reinforcement will then be explained in technical drawings.
