Sažetak
Results obtained by testing a cylindrical prestressed concrete shell subjected to long-term loading and unloading are presented. The shell is reinforced with steel fabric in the top and bottom zones, and features different reinforcement areas in two directions, as well as two straight prestressed longitudinal cables. It is attached at angles only, and lateral displacements are restrained. Shell displacements, and deformation of concrete in the zone of traditional reinforcement and cables, were measured at several points over one and a half year period following the initial prestressing and loading.
