Prestressed Concrete Practice Problems by Jefferson T. Ignacio is a document available to read on EtoBox.
1. A pretensioned concrete beam is prestressed with a 18m cable at 1040 MPa. Accounting for elastic elongation of steel, shrinkage of concrete, and elastic shortening of concrete, the required length of shims is calculated to be 100.98mm. 2. Immediately after transfer of prestress to a concrete section prestressed with 516mm2 of steel at 1040 MPa, the concrete stress is calculated to be 8.575 MPa and the steel stress is calculated to be 988.55 MPa. 3. For an eccentrically prestressed concrete section wit
