The Jakarta Light Rail Transit (LRT) East-West Corridor is one of the corridors recommended for DKI Jakarta railroad network in 2019-2039. This corridor is planned to accommodate passengers commuting from Pulo Gebang to Joglo. The construction of this corridor is divided into two phases, the 1st phase (Pulo Gebang-Karet) is 20,6 km long while the 2nd phase (Karet-Joglo III) is 12,35 km long. In this Thesis, the design is focused on the transportation aspects of the 1st phase, especially on the Depot-Klender Baru segment. The design is accomplished by creating structural preliminary design based on secondary data such as material specification and bridge specification, followed by analyzing structural calculation’s results due to LRT’s loading using SAP2000. The analysis is then used for designing prestress components on the girder (determination of prestressing forces, prestress losses, and analysis of stress and deflection), tendon layout, pier and pier head components, and superstructure components (girder and slab). Several software such as SAP2000, AutoCAD, pcaCol, and Microsoft Excel are utilized in this design. The Jakarta LRT East-West Corridor is planned to be consisted of segmental precast I-Girder (PCI Girder) with prestressed concrete material which is made of concrete material exerted with prestress force through a steel cable (tendon) and other supporting components namely pier, pier head, and slab using reinforced concrete. The bridge is adopting simply supported beam system on the PCI girder design. Furthermore, the analysis used to design the LRT bridge structure is a two-dimensional analysis by modelling girder, pier and pier head, and slab component separately.
