Sažetak
Firstly, the effect of classical reinforcement - prestressed reinforcement ratio on the behaviour of real concrete beams up to failure was experimentally investigated. The beams were 10m in length and 0, 5m in height, with following combination of classical and prestressed reinforcement: only classical reinforcement, dominant classical reinforcement and prestressed reinforcement, equal prestressed and classical reinforcement, dominant prestressed reinforcement and classical reinforcement and only prestressed reinforcement. The total amount of reinforcement in each beam was selected to provide their equal ultimate bending bearing capacity. Deflections, stresses in concrete, classical and prestressed reinforcement and concrete cracks were monitored until collapse of the beams. Main conclusions and recommendations for practical applications according to results of performed tests are given. Then, using the previously developed numerical model for static analysis of spatial frame structures [1, 2], which can simulate main nonlinear effects of their behaviour, numerical analysis of tested beams was performed. Good agreement was obtained between the experimental and the numerical results, which confirms the possibility of practical application of adopted numerical model.
