This paper focuses on understanding the concept of analysis and design of post-tensioned concrete bridges. For the
study, an existing reinforced concrete bridge near Khangaon village, Belagavi, which is in structurally poor condition, is
identified. Work has been carried out to propose a new post-tensioned prestressed concrete girder bridge with an increased
height for the above mentioned site. A post-tensioned girder bridge is designed by working stress method referring to IRC – 6,
IRC – 18, IRC – 21 and IS: 1343. Two cases have been studied and a parametric study has been carried out by altering the
effective span of the post-tensioned girder, one with an effective span of 30m and the other with 45m
