Abstract

Proyek Jembatan Bhayangkara merupakan bagian dari proyek pembangunan Jalan Tol Porong-Gempol. Jembatan Bhayangkara dibangun menggunakan sistem girder I pratekan. Oleh karena itu, dalam penulisan Tugas Akhir ini akan didesain ulang dengan merencanakan sistem gelagar berbentuk box multi cells precast pratekan. Gelagar box dibuat segmental cast in situ dengan ketinggian penampang box bervariasi mulai dari 2,5 – 7,2 meter. Perencanaan jembatan sesuai dengan peraturan RSNI T-02-2005 dan SNI T-12-2004. Untuk gempa menggunakan referensi SNI 2833:2016. Dari data perencanaan kemudian dilakukan preliminari desain yang mengacu pada buku manual dari FHA, “Box Girder Post Tension Manual.” Tahap awal desain adalah perhitungan struktur sekunder jembatan yaitu concrete barrier. Analisa beban terdiri dari analisa berat sendiri, analisa beban mati tambahan, dan beban lalu lintas. Kemudian dilakukan perhitungan analisa gaya dalam akibat sistem balanced cantilever dan sistem statis tak tentu. Selanjutnya dilakukan perhitungan penulangan box, kontrol lendutan, perhitungan geser, perhitungan kekuatan dan stabilitas yang meliputi kontrol momen retak, kontrol momen batas, kontrol gaya membelah, dan kontrol torsi. Hasil desain struktur berupa dimensi box, penempatan tendon, penulangan, pendetailan struktur yang dituangkan dalam bentuk tabel dan gambar teknik.

The Bhayangkara Bridge Project is part of the Porong-Gempol Toll Road construction project. The Bhayangkara Bridge was built using a prestressed I Girder system. Therefore, in the writing of this final project will be redesigned by assigning a box-shaped multicells girder prestressed system. The box girder is made segmental cast in situ with a cross section height varies from 2.5 - 7.2 m. Bridge design is in accordance with the regulations of the RSNI T-02-2005 and SNI T-12-2004. For earthquakes use the SNI 2833: 2016 reference. From the planning data then the preliminary design is carried out which refers to the manual of the FHA, "Box Girder Post Tension Manual." The initial stage of the design is the calculation of the secondary structure of the bridge namely concrete barrier. Load analysis consists of analysis of its own weight, analysis of additional dead loads and traffic loads. Then the calculation of internal force analysis is done due to the balanced cantilever system and indeterminate static systems. Next is the calculation of box reinforcement, deflection control, shear calculation, calculation of strength and stability including crack moment control, moment boundary control, splitting style control, and torque control. The structure design results in the form of box dimensions, tendon placement, reinforcement, detailed structure as outlined in the form of tables and technical drawings.
