Civil Read properly Q- Membersof the ACI Building Code committee conducted a study, and the results showed that the scatter in the modulus of elasticity did not support the use of a different or "more precise" formulation. As a result, the equation (Eci) can be applied generally. Calculations should be based on project mixture design test results if a project calls for a more exact estimation of the modulus of elasticity. Where f 0 ci is the strength of the concrete at the moment of transfer in psi and wc is the unit weight of the concrete in pcf, which is often taken to be 160 pcf for precast concrete and 150 pcf for cast-in-place concrete. Members with post-tension tensioning sequence affects elastic shortening in post-tensioned members. Tendons may be stressed to a maximum of 0.80 fpu, however the stress in the tendon right after seating must be 0.70 fpu or less. Calculate the fES for elastic shortening losses.
