WebApr 10, 2024 · The crack distribution of pre-cracked test beams at l /4 (the DSS1, DSS2 and DSS3 beam) is similar to that of the WS beam. Due to the stress concentration effect at l /4 position prefabricated cracks, beams DSS1, DSS2 and DSS3 have inclined cracks here, which develop along the beam height direction. The largest cracks in the test beam occur … WebAug 13, 2024 · The physical essence of the “nagel effect” for main reinforcement in an inclined crack of reinforced concrete structures for the model of deformation of reinforced concrete structures includes...

The Euler–Bernoulli beam model was assumed. Scanning was done around the simulated crack, to cover a square area of 30 mm × 30 mm, where the crack was approximately in the middle of the square. The PEC probe was then moved at an interval of 0.5 mm for the scanning purpose. Table 1 shows the parameters of the cracks. can hedgehogs eat raspberries
