Abstract

Jembatan Cimandiri berada pada jalur yang merupakan penghubung antara jalur lalu lintas Desa Tarisi dan Desa Hagarmaneh, Sukabumi.Jembatan ini mempunyai panjang bentang 80 m dan lebar 7 m. Alasan Dipilihnya Jembatan Beton Pratekan dengan Bentang Menerus pada perencanaan ini adalah pada segi dimensi. Jika dibandingkan dengan alternatif balok seperti statis tertentu, akan memerlukan dimensi yang cukup besar. Jembatan ini direncanakan dengan struktur beton pratekan, dimana gelagar/balok utama dibuatsecara precast dan lantai kendaraan dicor kemudian (cast in situ). Pada jembatan ini tersebut selain dipilih Jembatan Beton Pratekan balok dengan bentang menerus (statis tak tentu) juga di lihat dalam segi arsitektural. Tahap awal perencanaan adalah premilinary desain. Kemudian dilakukan perencanaan gelagar memanjang (balok pratekan) beserta jumlah tendon dan strandnya yang dilanjutkan perhitungan kehilangan akibat rangkak, susut beton, slip angker, lendutan serta kehilangan gaya prategang total dan juga didapatkan bentuk tendon parabola. Kemudian memasuki tahap akhir dari perencanaan struktur atas dilakukan perhitungan dimensi perletakan. ====================================================================================================== Cimandiri Bridge is located on a way as a connection between Tarisi Village and Hagarmaneh Village, Sukabumi. This bridge itself has 80 m length and 7 m width. The main reason of redesign this bridge structure into a prestressed concrete continuous beam system is more concern on dimensional section. If it is compared with another alternative beam system, such as simple beam statically determinate, simple beam design would absolutely give the bigger dimension output. This Bridge will be design with prestressed concrete where the main girder were precast girder, however the plate will be cor in conservative way. Instead of only seeing modification from one aspect, there also is a consideration from the architechtural perspective. The first step is preliminary design. And then followed by calculating the dimension of girder and the other main structure (include the amount of tendon and strands). After that, followed by loss of prestressed calculation which consist of creep, shrinkage, slip anchorage, etc. Finally, entering the last step of design which is the support calculation.
