Abstract

Pemakaian sistem modular merupakan salah satu teknologi yang layak dipertimbangkan. Sistem lantai modular baja merupakan sebuah sistem pabrikasi di mana pelat lantai dan balok dipabrikasi sekaligus dengan sistem drainase, mekanikal-elektrikal, dan finishing menjadi satu kesatuan modular. Keunggulan dari sistem ini yaitu constructability, mempunyai aspek positif terhadap penjadwalan, jumlah pekerja lapangan dan kantor proyek lebih sedikit, aspek kualitas dan produktivitas, dan pengujian.
Di China, BOARD Sustainable Building telah mengembangkan sistem lantai modular baja yang dapat menghasilkan pembangunan gedung yang sangat cepat, bahkan sebanyak 6 lantai dalam satu hari. Inovasi ini telah memenangkan Innovation Awards 2013 yang diselenggarakan oleh Council on Tall Buildings and Urban Habitat (CTBUH). Sistem lantai modular baja ini telah diterapkan oleh perusahaan BROAD Sustainable Building Co., LTD (BSB) dalam membangun gedung Hotel T30 yang berhasil didirikan selama 15 hari.
Dalam perencanaan ini, yang menjadi objek perencanaan adalah Gedung 88 Avenue Surabaya dengan memodifikasi struktur utamanya yaitu beton bertulang menjadi struktur baja 21 lantai dan 1 lantai basement. dengan menggunakan sistem lantai modular. Sistem lantai modular yang direncanakan mengacu pada sistem lantai modular pada Hotel T30 di Changsa, China. Perbedaannya yaitu pengecoran pelat lantai direncanakan dengan metode in situ.
Dalam kriteria desain struktur utama dan sambungan struktur baja direncanakan berdasarkan SNI 1729:2015 dan AISC 2016. Balok direncanakan dalam bentuk rangka batang menggunakan steel hollow section yang akan dirangkai dengan floor deck menjadi sebuah modular. Modular ini akan direncakan menjadi tiga bagian untuk memudahkan dalam transportasinya. Kolom yang digunakan berupa kolom komposit dalam bentuk concrete filled tube. Gaya lateral akan diterima oleh dinding geser pelat baja atau steel plate shear walls (SPSW) setebal 20 mm. Hal ini disebabkan oleh sendi plastis yang akan sulit terjadi di balok yang merupakan elemen aksial, sehingga sendi plastis direncakan untuk terjadi pada dinding gesernya. Tebal pelat lantai dan atap dengan menggunakan bondek adalah 12 cm, dimensi kolom CFT sebesar 600×600×25×25 Selain itu, perencanaan struktur gedung ini juga disertai perencanaan satu lantai basement dan pondasi. Dinding basement direncanakan setebal 30 cm dan pelat basement setebal 50 cm. Perencanaan pondasi menggunakan tiang pancang beton diameter 80 cm dengan kedalaman 28 meter. Dimensi sloof direncanakan dengan dimensi 400/600 mm.
================================================================================================
The application of modular system is one of the new technologies worth to be considered. Modular system is a prefabricated steel structure where the floor deck and beams are fabricated along with the drainage system, mechanical-electrical, and finishing in one modular. The benefits of this system are constructability, positive aspects towards schedule, less on and off site workers, quality and productivity aspects, and test.
In China, BOARD Sustainable Building had developed modular floor system resulting a very quick construction, reaching six floors in one day. This innovation has won the Innovation Awards 2013 held by Council on Tall Buildings and Urban Habitat (CTBUH). Modular system had been applied by BROAD Sustainable Building Co., LTD (BSB) in T30 Hotel construction and it took only fifteen days to finish the construction.
The object of this modified design is 88 Avenue Surabaya. The existing structure is modified into a composite structure with steel plate shear wall (SPSW) as the lateral force resistant element using modular floor system methods. The methods of modular floor systems are referring to modular system methods of T30 Hotel in Changsa, China. The concrete deck casting is designed to be done in in situ methods.
Design criteria of the primary structure and connection is based on SNI 1729:2015 and AISC 2016. The beam is designed as a truss element using steel hollow section and to be assembled with steel floor deck into a modular. This modular is designed in three separated parts in order to make the transportation process easier. The columns are designed using concrete filled tube (CFT) as a composite element. The lateral forces will be resisted by 20 mm SPSW in consideration of modular elements as axial members in which the plastic hinges are unlikely to be formed. Thus, the plastic hinges are to be formed in SPSW. The thickness of roof and floor decks are 12 cm. The column is to be designed using CFT 600×600×25×25. Other than that, the design of this building structure is including the basement and foundation planning. Basement wall is 30 cm in thickness and basement deck is 50 cm in thickness. The design of the foundation uses concrete spun pile with 80 cm in diameter and 28 meters in depth. The tie beam is designed to be 400 mm in width and 600 mm in depth.
