engineering recuitment TNPSC AE Civil 2024 Test series Reinforced Concrete Structures Prestress Concrete
In a simply supported prestressed concrete beam subjected to uniformly distributed load on entire span, the ideal shape of the cable profile will be
1
concentric with the center of cross-section
2
at constant eccentricity over the entire span
3
varying linearly with zero eccentricity at ends and maximum eccentricity at mid-span
4
parabolic with zero eccentricity at ends and maximum eccentricity at mid-span
