| Abstract: In this research, an analytical model is presented to study the shear behavior of prestressed hollow core slabs. The study is conducted with respect to the shear considering a concentrated line load (in absence of concrete topping and filling of cores) using finite elements method adopted by the computer program ANSYS. The finite element models are developed using a smeared cracking approach for the concrete and three-dimensional link elements for the prestressing strands. The ANSYS finite element analysis results are compared with the experimental data of two prestressed hollow core slabs. The comparisons are made for load-deflection curves, failure load and crack pattern. The accuracy of the finite element models is assessed by comparison with the experimental results, which are to be in good agreement. | ||
