Abstract:
The analysis of the strength ability of beams with shear stirrups involves problems with complex interactions between parameters. This paper introduces a new formulation to verify the shear strength of beams with stirrups for diagonal tensile burst by univariate power regressions to evaluate the preponderance of degrees of the most common shear factors from an initial database with 90 beams. Analyzing the performance of the standards codes, empirical models, and theoretical models with another 160 different tests and a seven-beam experimental program designates the accuracy of the models.
