engineering recuitment MP Vyapam Sub Engineer Mock Test 2024 Reinforced Concrete Structures Prestress Concrete
A simply supported post-tensioned prestressed concrete beam of span L is prestressed by a straight tendon at a uniform eccentricity ‘e’ below the centroidal axis. If the magnitude of prestressing force is ‘P’ and flexural rigidity of beam is ‘EI’, the maximum central deflection of the beam is
1
\(\frac{{Pe{L^2}}}{{8\;EI}}\) (Upwards)
2
\(\frac{{Pe{L^2}}}{{16\;EI}}\) (Downwards)
3
\(\frac{{Pe{L^2}}}{{16\;EI}}\) (Upwards)
4
\(\frac{{Pe{L^2}}}{{8\;EI}}\) (Downwards)
