(Georgia)

The results of test on bridge 27 m long prestressed reinforced concrete beams have been presented. Operational fitness of beams has been estimated according to the second limited state, in particular, by comparison of the received values of diflection with theoretically calculated ones. All tested beams satisfy the project specifications.

Loading redistribution diagrams in tested beams have been presented. It has been stated that before operational loading in beam stretched zone the concrete is gradually liberated from prestressing and it doesn't participate in beam working. Outside loading is completely balanced by prestressed reinforcement.
