Abstract

Pada perencanaan jembatan beton prategang menggunakan I girder sebagai struktur utamanya. Bentang jembatan section 0-152 adalah 80 m terbagi dalam jarak masing-masing 40 m. Dasar perencanaan struktur PCI Girder dan pembebanan jembatan mengacu pada Brigde Management System ( BMS, 1992), dengan tegangan ijin dari PCI girder mengacu *pada* SNI* 03-2847-2002. Analisa* pembebanan* beban mati, beban hidup, beban angin dan analisa pengaruh* waktu* seperti* rangkak, susut* dan kehilangan *prategang. Dari* analisa* perhitungan *balok* induk *berbentu* I diperoleh Lebar jembatan yang direncanakan* 2 lajur 1* arah, lebar per arah 3,5 meter. Disisi kanan kiri jalan terdapat concrete barrier dengan lebar 0,6 meter. Perencanaan ini dimulai dengan pengumpulan data-data teknis yang diperlukan dalam perencanaan. dilanjutkan dengan penjelasan mengenai latar belakang, pembahasan, dan dasar-dasar perencanaan yang mengacu pada peraturan perencanaan jembatan RSNI T-02- 2005, SNI T-12-2004, dan ASTM A-416. setelah itu barulah dilakukan preliminary design dengan menentukan dimensi-dimensi utama jembatan. Pada tahap awal perencanaan dilakukan perhitungan terhadap struktur sekunder jembatan seperti : pagar pembatas dan lantai kendaraan yang nantinya akan digunakan untuk analisa beban yang terjadi. Analisa beban yang terjadi seperti : analisa berat sendiri, beban mati tambahan, beban lalu lintas, dan analisa pengaruh waktu seperti creep dan kehilangan gaya prategang. Kemudian dari hasil analisa tersebut dilakukan kontrol tegangan yang terjadi pada struktur. Tahap yang terakhir dari perencanaan ini adalah perencanaan perletakan. Akhir dari perencanaan ini adalah didapat bentuk dan dimensi penampang I girder yang mampu menahan beban-beban yang bekerja pada jembatan, sehingga didapat suatu struktur jembatan yang aman. Kata Kunci : Jembatan, beton prategang, PCI girder. ABSTRACT In prestressed concrete bridge planning using I girder as the main structure. The span of the bridge section 0-152 is 80 m divided into 40 m each. The basis for planning the PCI girder structure and bridge loading refers to the Bridge Management System (BMS, 1992), with the voltage of the PCI girder referring to SNI 03-2847-2002.Load analysis, namely dead load, live load, wind load, and analysis of the effects of time such as crawling, shrinkage, and loss of prestress. From the analysis of the calculation of the main beam with I shape, it is obtained that the planned bridge width is 2 lanes in 1 direction, with a width per the direction of 3.5 meters. On the right and left side of the road, there is a concrete barrier with a width of 0.6 meters. This planning begins with the collection of technical data needed in planning. Then proceed with an explanation of the background for selecting the bridge, the formulation of planning objectives, discussion, and the basics of planning that refer to the RSNI T-02-2005 bridge planning rules, SNI T-12-2004, and ASTM A-416. After that, a preliminary design is carried out by determining the main dimensions of the bridge.In the early stages of planning, calculations are carried out on the secondary structure of the bridge such as guardrails and vehicle floors which will later be used for load analysis. Load analysis such as self-weight analysis, additional dead load, traffic load, and analysis of time effects such as creep and loss of prestressing force. Then from the results of the analysis, stress control that occurs in the structure is carried out. The last stage of this planning is placement planning. The end of this planning is to obtain the shape and dimensions of the I girder cross-section that can withstand the loads acting on the bridge so that a safe bridge structure is obtained. Keywords: Bridge, prestressed concrete, PCI girder.
