Abstract:
One-way slabs under concentrated loads may develop different shear failure mechanisms. This study examines the benefits of using Linear Elastic Finite Element Analyses (LEFEA) combined with analytical expressions based on the Critical Shear Crack Theory (CSCT) to predict the shear and punching capacities of such slabs. Besides, the predictions of the most critical shear failure mechanism were also addressed. The results indicate the coupling of the CSCT-expressions with the LEFEA accurately predicts the governing shear failure mechanism and the shear capacity of most test results. Moreover, a similar level of precision was achieved using only analytical expressions when properly calibrated.
