Figure 7.12 Analysis of instantaneous and time-dependent strain and stress in a
pre-tensioned cross-section before cracking (Example 7.5); (a) cross-
section dimensions; (b) strain and stress immediately after prestress
transfer; (c) changes in stress and strain due to creep, shrinkage and
relaxation.
