Abstract

Perencanaan Struktur Gedung My Tower Surabaya setinggi 20 lantai (+82,55 m) akan dimodifikasi menggunakan beton prategang pada lantai 5 yang akan didesain menjadi ballroom tanpa ada struktur kolom di tengah ruangan sehingga ballroom menjadi lebih nyaman dan luas dibandingakan dengan penggunaan balok non prategang yang akan menghasilkan dimensi yang lebih besar. Di Indonesia, pembangunan suatu gedung harus memenuhi standar gedung yang tahan gempa, mengingat wilayah Indonesia termasuk ke dalam kawasan ring of fire dimana sering terjadi pergerakan lempeng yang mengakibatkan gempa. Dalam perencanaannya, struktur Gedung My Tower Surabaya ini menggunakan Sistem Ganda. Sistem Ganda (dual system) adalah salah satu sistem struktur yang beban gravitasinya dipikul sepenuhnya oleh rangka utama, sedangkan beban lateralnya dipikul bersama oleh rangka utama dan dinding struktur. Rangka utama dan dinding struktur didesain sebagai Struktur Rangka Pemikul Momen Khusus (SRPMK) dan Dinding Struktur Beton Khusus (DSBK). Dari hasil analisa yang telah dilakukan, didapatkan kesimpulan bahwa rangka utama gedung mampu menahan beban lateral arah X sebesar 25,09% dan arah Y sebesar 28,55% sehingga syarat Sistem Ganda terpenuhi. Gaya prategang didapat sebesar 5.116,45 kN dengan kehilangan gaya prategang sebesar 27,16%. =================================================================================================== Building planing of My Tower Surabaya Apartemen as high as 20 floors (+82,55 m) will be modified using prestressed concrete beam on the 5th floor which will be designed as ballroom without any coloumn in the middle of the ballroom so it will be more comfortable and has wide view than using non prestressed beam that will produce a larger dimension. In Indonesia, the building construction must be designed as Eartquake-Resistant Building Standard, given of Indonesia’s position at the ring of fire where the movement of the plates often happens that cause earthquakes. The structure design of My Tower Surabaya will use dual system method, where the gravity loads will be resists by main frame, and the lateral loads will be resists by shearwall and frame at the same time. The main frame will be designed as Special Moment Frame System Bearers and the shearwall will be designed as Special Structural Wall. From the analysis result, it was concluded that the main frame is able to withstand 25,09% of the lateral loads at X direction and 28,55% at the Y direction, so Dual System requirements are met. Prestressed force obtained at 5.116,45 kN and has loss of prestresing force at 27,16%.
