Abstract

Gedung Psikologi Universitas Islam Negeri Sunan Ampel II yang terletak di Surabaya, Jawa Timur merupakan gedung beton bertulang 9 lantai dengan sistem rangka pemikul momen khusus (SPRMK) yang akan direncanakan desain alternatif menggunakan sistim rangka pemikul momen biasa (SRPMB) dan base isolator sebagai tambahan peredam gempa. Dalam hal ini dikarenakan gedung berada pada tanah Surabaya yang diketahui merupakan tanah lunak (SE), maka desain alternatif pada Gedung Psikologi Universitas Islam Negeri Sunan Ampel II yang awalnya terletak di Surabaya dipindah ke Malang yang merupakan daerah tanah sedang, sangat padat dan batuan lunak (SD). Penggunaan metode base isolator dinilai menjadi peredam gempa yang cocok digunakan di daerah rawan gempa dan dapat mereduksi beban gempa yang terjadi. Pertimbangan perencanaan dengan metode base isolator ini juga berkembang seiring dengan perubahan SNI 1726:2019 “Tata Cara Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung Dan Nongedung” Nilai respon spektrum SNI 1726:2019 yang lebih besar dari pada SNI 1726:2012 mempengaruhi kinerja struktur Gedung Psikologi Universitas Islam Negeri Sunan Ampel II dalam menahan gempa. Langkah pertama pada perencanaan ini berupa pengumpulan data-data eksisting, pembebanan dan membuat preliminary gedung dengan penambahan base isolator pada program bantu ETABS 2019 sesuai dengan data eksisting yang sebelumnya sudah didapatkan. Permodelan terdiri dari permodelan eksisting SRPMK, dan permodelan SRPMB dengan base isolator. Untuk permodelan pada gedung SRPMB dan base isolator dianalisa dengan pembebanan gempa respon spektrum komposit. Hasil perhitungan yang sudah memenuhi kontrol struktur dan kontrol penulangan selanjutnya akan dijelaskan pada penggambaran teknik dan kemudian melakukan kontrol dinamis sesuai dengan peraturan SNI 1726:2019. Tugas akhir ini mendapatkan hasil bahwa gaya geser dasar gempa (Base Shear) untuk bangunan sistem rangka pemikul momen khusus (SRPMK) sebesar 4889,26 arah X dan Y, untuk bangunan sistem rangka pemikul momen biasa (SRPMB) 14810,95 untuk arah X dan Y, untuk desain alternatif struktur SRPMB tambahan Base Isolator HH120X6R gaya geser gempa sebesar 5553,78 untuk arah X, 6265,23 untuk arah Y. Didapatkan reduksi sebesar 63% arah gempa X dan 58% arah gempa Y. Selain itu penambahan base isolator dinilai efektif dalam pengurangan simpangan antar lantai. ==================================================================================================== The Psychology Building of Sunan Ampel II State Islamic University located in Surabaya, East Java is a 9-story reinforced concrete building with a special moment resisting frame system (SPRMK) which will be planned for an alternative design using an ordinary moment resisting frame system (SRPMB) and a base isolator as an additional damper. earthquake. In this case because the building is located on Surabaya soil which is known to be soft soil (SE), then the alternative design of the Psychology Building of the State Islamic University of Sunan Ampel II which was originally located in Surabaya was moved to Malang which is an area of medium soil, very dense and soft rock (SD). The use of the base isolator method is considered to be an earthquake absorber which is suitable for use in earthquake-prone areas and can reduce earthquake loads that occur. Planning considerations with the base isolator method also developed along with the changes in SNI 1726:2019 "Procedures for Planning Earthquake Resistance for Building Structures and Buildings" The value of the spectrum response of SNI 1726:2019 which is greater than SNI 1726:2012 affects the performance of the building structure. Psychology of the State Islamic University of Sunan Ampel II in resisting earthquakes. The first step in this planning is in the form of collecting existing data, loading and making building preliminary with the addition of a base insulator in the 2019 ETABS aid program in accordance with existing data that was previously obtained. The modeling consists of the existing SRPMK modeling, and the SRPMB modeling with a base isolator. For the modeling of the SRPMB building and the base isolator, it is analyzed by using the composite spectrum response earthquake loading. The calculation results that have met the structural control and reinforcement control will then be explained in the technical drawing and then perform dynamic control in accordance with SNI 1726:2019 regulations. This final project results that the basic seismic shear force (Base Shear) for the special moment resisting frame system (SRPMK) is 4889.26 in the X and Y directions, for the ordinary moment resisting frame system (SRPMB) 14810,95 for the X and Y directions. Y, for the alternative design of the SRPMB structure, the additional Base Isolator HH120X6R earthquake shear force of 5553,78 for the X direction, 6265,23 for the Y direction. There was a 63% reduction in the X direction of the earthquake and 58% in the Y direction. In addition, base isolator was assessed effective in reducing the drift between floors.
