Abstract

Indonesia has exceptionally high seismic activity. It is because Indonesia is an archipelagic country located at the intersection of three active tectonic plates: the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate. The earthquake had a devastating effect in terms of material damage and loss of life. In general, the number of casualties was caused by falling building debris. Therefore, to mitigate the effects of an earthquake, the building structure must be designed to withstand them.
Composite structures have several benefits, such as being more substantial and rigid than non-composite structures, enhancing structural performance, reducing material costs, and reducing processing times. Nevertheless, an earthquake-resistant structural system known as Eccentrically Braced Frames (EBF) has excellent elastic stiffness, good ductility, and the ability to absorb high energy. The main principle underlying the EBF structure is that the link element is designated as the yielding component, while the other elements are anticipated to maintain their elasticity.
In this final project proposal, the 22-floor Nayumi Sam Tower Apartment in Malang, which was initially made of reinforced concrete, will be modified to a steel-concrete composite structure with an EBF system, and the number of floors will be reduced to 20. The employed EBF configuration is Inverted-V Braced. This plan complies with SNI 1729-2015, AISC 341-10, SNI 1726-2019, SNI 1727-2018, and SNI 2847-2019 structural safety requirements.
===================================================================================================================================
Indonesia memiliki aktivitas gempa bumi yang sangat tinggi. Hal ini disebabkan karena Indonesia merupakan negara kepulauan yang terletak di persimpangan tiga lempeng tektonik aktif: Lempeng Eurasia, Lempeng Indo-Australia, dan Lempeng Pasifik. Gempa bumi memiliki dampak yang sangat merusak baik dari segi kerusakan material maupun hilangnya nyawa. Secara umum, jumlah korban jiwa disebabkan oleh reruntuhan bangunan yang roboh. Oleh karena itu, untuk mengurangi dampak gempa bumi, struktur bangunan harus dirancang agar mampu bertahan terhadapnya.
Struktur komposit memiliki beberapa keuntungan, seperti lebih kokoh dan kaku dibandingkan struktur non-komposit, meningkatkan kinerja struktural, mengurangi biaya material, dan mengurangi waktu pengolahan. Namun, sistem struktural tahan gempa yang dikenal sebagai Eccentrically Braced Frames (EBF) memiliki kekakuan elastis yang sangat baik, keuletan yang baik, dan kemampuan untuk menyerap energi tinggi. Prinsip utama yang mendasari struktur EBF adalah elemen penghubung ditunjuk sebagai komponen yang dapat meleleh, sementara elemen-elemen lainnya diharapkan dapat mempertahankan elastisitasnya.
Dalam proposal proyek akhir ini, Apartemen Nayumi Sam Tower berlantai 22 di Malang, yang awalnya terbuat dari beton bertulang, akan dimodifikasi menjadi struktur komposit baja-beton dengan sistem EBF, dan jumlah lantainya akan dikurangi menjadi 20. Konfigurasi EBF yang digunakan adalah Braced Inverted-V. Rencana ini sesuai dengan persyaratan keamanan struktural SNI 1729-2015, AISC 341-10, SNI 1726-2019, SNI 1727-2018, dan SNI 2847-2019.
