Abstract: Perkembangan beton prategang semakin berkembang pesat seiring meluasnya teknologi konstruksi. Penggunaan beton prategang sangat mendukung pembangunan infrastruktur Indonesia, khususnya Jalan Layang Kereta Api Kualanamu di kota Medan yang menggunakan Box Girder dengan tinggi penampang 2400 mm sebagai komponen strukturalnya. Studi kasus beton prategang box girder Jalan Layang Kereta Api Kualanamu dengan bentang 40 meter menjelaskan keefektifitasan penampang girdernya yang memiliki tendon – tendon internal yang diisi kabel baja strand dia. 12,7 mm berjumlah 60 buah. Selanjutnya menganalisa persentase kehilangan gaya prategang yang terjadi pada tendonnya akibat perpendekan elastis, gesekan pada tendon, rangkak, susut pada beton dan sebagainya. Sebagai tambahan diperkenalkan langkah – langkah proses produksi beton prategang box girder mulai dari penulangan sampai pengecoran di pabrik beton pracetak.
Description: The development of prestressed concrete is growing rapidly as the widespread construction technology . The use of prestressed concrete supports infrastructure development in Indonesia , especially Kualanamu Railway overpass in the city of Medan that use Box Girder with sectional height 2400 mm as a structural component . The case study of prestressed concrete box girder Railway flyover with spans of 40 meters Kualanamu explain sectional effectiveness girders where are internal tendons filled her strand steel cables. 12.7 mm totaling 60 pieces. Further analyzing the percentage loss of prestressing force that occurs in the tendon due to the shortening of the elastic , friction on the tendon , creep , shrinkage of the concrete and so on. Additionally introduced step by step production process prestressed concrete box girder ranging from reinforcement to casting in the precast concrete plant .
