Abstract

Light Rail Transit atau LRT Jakarta adalah transportasi massal bermoda kereta yang dibangun di Jakarta, Indonesia. Struktu LRT direncanakan dengan struktur melayang pada ketinggian 9-12 meter diatas permukaan tanah meggunakan U-shape Girder. Perencanaan jembatan ini dimulai dengan pengumpulan data dan literatur yang diperlukan dalam perencanaan. Perencanaan akan mengacu pada SNI T-12-2004 dan Standar Teknis Kereta Api Indonesia. Pada tahap awal perencanaan dilakukan preliminary desain untuk menentukan dimensi struktur utama penampang u-shape girder berdasarkan bentang jembatan. Selanjutnya dilakukan perhitungan terhadap struktur sekunder jembatan. Analisa pembebanan yang terjadi diantaranya akibat: berat sendiri, beban mati tambahan, beban kereta, serta mempertimbangkan pengaruh terhadap waktu seperti kehilangan gaya prategang. Kemudian dari hasil analisa tersebut dilakukan kontrol tegangan akhir yang terjadi pada struktur u-shape girder, perhitungan penulangan, serta perhitungan kekuatan dan stabilitas. Hasil akhir dari tugas akhir ini adalah bentuk dan dimensi penampang u-shape girder, pier, dan pondasi yang sesuai beserta detail penulangannya. Serta menentukan letak tendon pada penampang yang dituangkan dalam bentuk tabel dan gambar. ================================================================= Light Rail Transit or LRT Jakarta is a mass transportation by train built in Jakarta, Indonesia. LRT structure is planned with a floating structure elevated at 9-12 meters above ground using U-shape Girder. The planning of this bridge begins with the collecting of data and literature required in planning. Planning will refer to SNI T-12-2004 and Indonesian Railway Technical Standard. In the early stages of planning preliminary design is done to determine the main structure dimension of the u-shape girder cross section based on the span of the bridge. Next is calculated on the secondary structure of the bridge. The load analysis that occurs is due to: own weight, additional dead load, train load, and consider the effect on time such as loss of prestressing style. Then from the results of the analysis is done the final stress control that occurs in the structure of u-shape girder, calculation of reinforcement, as well as calculation of strength and stability.The result of this final project is the shape and dimension of the correct shape of the u-shape girder, pier, and foundation along with the detail of the reinforcement. Determine the location of the tendon on the cross section which is showed in the form of tables and pictures.
