Abstract
Seiring dengan pertambahan umur jembatan dan peningkatan volume lalu lintas, terjadi penurunan daya layan dan ketahanan jembatan yang berpengaruh pada peningkatan tegangan elemen jembatan dan pertambahan lendutan. Perkuatan jembatan rangka dengan metode prategang eksternal menggunakan kabel diharapkan dapat untuk mereduksi tegangan batang struktur jembatan, sehingga kapasitas jembatan dapat meningkat dengan gaya prategang yang optimum. Jembatan Rangka Baja Bogo-Bogo terletak pada ruas jalan Trans Sulawesi yang menjadi penghubung antara kecamatan Marisa dengan kecamatan Tolinggula dengan bentang 60 meter dan lebar total jembatan 9 meter. Semula jembatan ini direncanakan mampu menahan beban BM 70 dan kini penulis merencanakann sekaligus menganalisa ulang dengan pembebanan BM 100 (kombinasi terkini) dengan gempa 2016, dan penulis juga memperkuat struktur atas jembatan ini khususnya bagian rangka utama dengan menambahkan kabel prestressed eksternal. Jembatan ini menggunakan rangka tipe ‘standard warren truss’ dan digunakan sebagai objek tugas akhir untuk menguraikan hasil studi ketahanan dan kelayakan jembatan existing apabila direncanakan dengan pembebanan terbaru yang mana jembatan tersebut sebagai akses utama Trans Sulawesi. Menganalisa struktur jembatan bangunan atas meliputi konfigurasi rangka jembatan eksisting. Sedangkan analisa bangunan bawah meliputi pondasi sumuran. Analisa tersebut mengacu pada SNI T-12-2004, SNI 1725-2016 dan pembebanan gempa mengacu pada SNI Gempa 2833-2016 (Jembatan)

Along with increasing bridge life and increasing traffic volume, there is a decrease in bridge service and durability which has an effect on increasing the bridge element voltage and increasing deflection. Strengthening the truss bridge with an external prestressed method using cables is expected to be able to reduce the tension of the bridge structure, so that the bridge capacity can increase with the optimum prestressing force. The Bogo-Bogo Truss Bridge is located on the Trans Sulawesi road section which is a liaison between the Marisa sub-district and Tolinggula sub-district with a span of 60 meters and a total width of 9 meters bridge. Initially the bridge was planned to be able to hold BM load 70 and now the author plans at the same time to reanalyze with the loading of BM 100 (the latest combination) with the 2016 earthquake, and the author also strengthens the structure of this bridge, especially the main frame by adding external prestressed cables. This bridge uses the framework of the 'standard warren truss' type and is used as the final project object to describe the results of the resilience and feasibility study of the existing bridge if planned with the latest loading which is the main access to the Trans Sulawesi bridge. Analyzing the structure of the bridge of the upper building includes the configuration of the existing bridge frame. While the analysis of the lower building includes the foundation of the well. The analysis refers to SNI T-12-2004, SNI 1725-2016 and earthquake loading refers to SNI Earthquake 2833-2016 (Bridge)
