Abstract
Abstrak
Gedung Apartemen Puncak CBD merupakan hunian vertikal yang terdiri dari 37 lantai untuk unit kamar yang terletak di daerah Wiyung, Surabaya Barat. Apartemen ini dibangun dengan struktur beton bertulang biasa pada keseluruhan lantai dan dilakukan modifikasi pada lantai atap. Modifikasi ini bertujuan untuk mengubah lantai paling atas gedung menjadi suatu ruang serbaguna.
Ruang serbaguna didesain memiliki panjang 30 meter dan lebar 13,65 meter dimana kolom-kolom interior ruangan akan dihilangkan dan digantikan fungsinya oleh balok pratekan agar luas ruangan menjadi optimal. Metode beton pratekan yang digunakan dalam modifikasi ini adalah metode post tension (pasca tarik) yang cocok diterapkan pada konstruksi gedung. Perencanaan gedung ini juga menggunakan Sistem Ganda karena apartemen terletak di Kategori Desain Seismik D.
Dari hasil analisa yang telah dilakukan didapatkan kesimpulan bahwa syarat Sistem Ganda pada Apartemen Puncak CBD dapat terpenuhi. Rangka utama gedung mampu menahan beban lateral X dan Y minimum 25% dari total gaya gempa, yaitu sebesar 29,63% dan 27,39%. Gaya pratekan yang dikenakan pada balok pratekan lantai atap pada saat jacking adalah sebesar 1840 kN dengan kehilangan gaya sebesar 19,06%.

Abstract
Puncak CBD Apartment Building is a vertical dwelling consisting of 37 floors for room unit located in Wiyung, West Surabaya. The apartment was built with a regular reinforced concrete structure on the entire floor and modified on the roof floor. This modification aims to turn the top floor of the building into a multipurpose room.
The multipurpose room is designed into 30 meters length and 13.65 meters wide where the interior columns of the room will be removed and replaced by prestressed beams to optimize the space. The prestressed concrete method used in this modification is post tension method which is suitable to be applied to building construction. This building design also uses Dual Systems because the apartment is located in the Seismic Design Category D.
From the result of analysis that have been done, Puncak CBD Apartment fulfilled the requirement of Dual System. The main frame of building is able to withstand minimum 25% total lateral load, which the result is 29,63% for X direction and 27,39% for Y direction. The prestressed force applied to the beam at the time of jacking is 1840 kN with has 19,06% loss of prestressed.
