Abstract

Metode pracetak saat ini telah banyak digunakan dalam pembangunan konstruksi sipil. Hal ini terjadi karena beton pracetak memiliki beberapa kelebihan dibandingkan beton yang dicor di tempat (cast in situ). Kelebihan tersebut meliputi waktu pengerjaan yang relatif singkat, proses produksinya tidak tergantung cuaca, tidak memerlukan tempat penyimpanan material yang luas, kontrol kualitas beton lebih terjamin, hemat akan bekisting dan penopang bekisting, serta kemudahan dalam pelaksanaannya sehingga dapat mereduksi durasi proyek dan secara otomatis biaya yang dikeluarkan menjadi lebih kecil.
Gedung Apartemen Menara Rungkut Tower B berada di Jalan K. Abdul Karim No. 37-39 Surabaya yang terdiri dari 15 lantai. Berdasarkan hasil Standart Penetration Test (SPT), gedung tersebut dibangun diatas tanah lunak (kelas situs SE) yang termasuk Kategori Desain Seismik D. Bangunan eksisting dibangun dengan sistem rangka pemikul momen khusus dan dilakukan pengecoran di tempat. Bangunan akan dimodifikasi menggunakan elemen pracetak hanya pada balok dan pelat tidak termasuk balok lift, balok dan pelat kantilever, balok tangga dan pelat tangga. Sedangkan komponen lain menggunakan metode cor ditempat. Dalam perencanaan pracetak perlu dilakukan kontrol terhadap beton pracetak tersebut saat proses pengangkatan, penumpukan, pemasangan, dan pengecoran in situ.
Modifikasi proyek akhir ini mengacu pada Tata Cara Perancangan Beton Pracetak dan Beton Prategang untuk Bangunan Gedung (SNI 7833-2012), Persyaratan Beton Struktural untuk Bangunan Gedung (SNI 03- 2847-2013) dan PCI Design Handbook Precast & Prestressed Concrete 6th Edition. Untuk desain gempa berdasarkan pada Tata Cara Perencanaan Ketahanan Gempa untuk Struktur Bangunan Gedung dan Non Gedung (SNI 03-1726-2019) dan Beban Minimum untuk Perancangan Bangunan Gedung dan Struktur Lain (SNI 03-1727-2013), serta peraturan penunjang lainnya.
Hasil perhitungan berupa penulangan struktur dan desain sambungan. Hasil desain struktur gedung gedung Apartemen Menara Rungkut Tower B meliputi tebal pelat 12 cm, meliputi ukuran balok induk 50/70 dan 60/80, ukuran balok anak 25/40, dan ukuran kolom 70/85 cm. Sambungan antar elemen menggunakan sambungan basah dan konsol pendek. Sambungan basah berupa pengecoran overtopping setebal 4 cm untuk pelat dan 12 cm untuk balok.

Precast method nowadays has been used in many civil constructions. The precast concrete has advantages to be compared to cast in situ concrete. Those advantages encompass brief processing time, the production process not depending at weather, unnecessary too much space of material storage, guaranteed quality control of the concrete, scanty amount of formwork, and the least but not least, the ease of implementation can reduce the project duration and also the project cost that needed is smaller.
Menara Rungkut Tower B Apartment Building is located at Jalan K. Abdul Karim No. 37-39 Surabaya, which consists of 15 floors. Based on the results of the Standard Penetration Test (SPT), the building was built on soft ground (SE site class) which is included in the Seismic Design Category D. This building is designed using a Special Moment Bearer Frame System (SRPMK) and using in situ concrete pouring method . The building will be modified using precast elements only on beams and slabs excluded lift beams, cantilever beams and slabs, stair beams and slab. Meanwhile, other components used the insite cast method. In precast planning it is necessary to control the precast concrete during the lifting, stacking, installation, and in situ casting processes.
This final project modification refers to the Design Procedures for Precast Concrete and Structured Concrete for Buildings (SNI 7833-2012), Requirements for Structural Concrete for Buildings (SNI 03-2847-2013) and the PCI Design Handbook Precast & Prestressed Concrete 6th Edition. For earthquake design based on Earthquake Resistance Planning Procedures for Building and Non-Building Structures (SNI 03-1726-2019) and Minimum Load for Designing Buildings and Other Structures (SNI 03-1727-2013), as well as other supporting regulations.
The results are in the form of structural reinforcement and joint design. The results of the structural design of the Menara Rungkut Tower B apartment building are thickness of slab is 12 cm, the dimension of the primary beams 50/70cm and 60/80cm, the dimesnion of secondary beams 25/40cm, and dimension of column 70/85 cm. Connector between precast elements using wet connection and bracket. Wet connection is using overtopping casting as thick as 4 cm for slabs and 12 cm for beams.
