Time-dependent internal forces in uncracked structures: analysis by the displacement method - Concrete Structures: Stresses and Deformations - page 163

Figure 5.9 Analysis of internal forces caused by shrinkage in the composite
continuous frame of Example 5.2: (a) resultants of stresses to restrain
shrinkage of concrete at the ends of members AB, BC or CD; (b) stress
distribution in any section of AD at time t 1 if shrinkage were fully
restrained; (c) forces in (a) assembled and applied in a reversed direction
on the continuous frame (the reactions corresponding to the applied
forces are included in the figure); (d) bending moment and axial force
diagrams for the frame in (c).
