Probabilistic analysis of the cracking of RC beams

Three beams of rectangular cross-section and having same cross-sectional dimensions were tested in two-point bending, over an effective span of 4.2 m. All three beams contained steel only in the tension zone and the tension steel was distributed in three different ways. A deterministic analysis of strains, crack spacings and crack widths for all three beams is carried out and the results are compared with the respective experimental values. A probabilistic analysis of strains, crack spacings and crack widths is performed for all the three beams at different stages of loading.
