Verification of Strut Angles
The 18 tests with strut rotation measurements by Walraven et al. (2013) are applied to compare with the analytical results. These I-shaped beams were made of various types of concrete, with a wide range of ω between 0.04 and 0.46. A system of linear variable differential transformers (LVTDs) was arranged in triangles at the web to measure the strains along different directions, which were used to estimate the strut rotation angle by means of Mohr’s circle.
