CE6702 Prestressed concrete structures, Final year

A Prestressed concrete beam supports a live load of 4 KN/m over a simply supported span of 8 m. The beam has an I- section with an overall depth of 400 mm. The thickness of the flange and web are 60 and 80 mm, respectively. The width of the flange is 200 mm. The beam is to be prestressed by an effective prestressing force of 235 KN at a
