Study of concrete under combined shear compression loading. Evaluation of cracking tangential stress

This study presents an experimental method for evaluating the cracking tang ential stress of concrete tested under shear-compression loading. This meth od consists in presenting the tests carried out on full cylinders in a loca l response - global response diagram and in determining the loss of strain homogeneity. A comparison of the results to the BPEL's criterion (the Frenc h code of practice) shows that OUT results are slightly lower than the crit erion but included in the safety area of utilization of this criterion.
