Question 02:- End Section Mid Section C Span 20m, Super imposed load g= 5.0kN/m, dead load q= 8.0kN/m, tendon profile is parabolic. Use BS8110 load combination Determine A. What is the maximum prestressing force at mid span section to ensure that the stresses in the bottom fiber does not exceed the allowable stress of 0.4 fcu? With this maximum amount of prestress calculate the stress at top fiber at mid span section and show that does not exceed the allowable tensile stress of 0.25fcu B. What is the minimum prestressing force at mid span section to ensure that there is no tension at the bottom fiber ? With this maximum amount of prestress calculate the stress at top fiber at mid span section and show that does not exceed the allowable tensile stress of 0.45fcu
