In this experimental program, shear tests were conducted on beams with shear reinforcement ratio in the range of 0.6–1.6 times the minimum shear reinforcement (ρw,min) according to EC2. The program consisted of four simply supported beams subjected to point loads, three simply supported beams and four cantilevers subjected to uniform loads. The test results showed a considerable influence of the static system and loading condition on the crack pattern and load bearing capacity of the tested beams. While a reinforcement ratio lower than ρw,min had almost no influence on the shear resistance of beams with point loads, a low ration of shear reinforcement corresponding to 0.6ρw,min could significantly enhance the shear resistance of beams with uniform loads. With an application of innovative measuring methods, changes in the flow of forces in beams at diverse loading levels could be analyzed.
