Numerical Analysis of One-Way Flexural Strength of Voided Slab
This article presents a nonlinear finite element approach on the one-way flexural strength determination of biaxial hollow slabs (voided slab). Voided slab appears as traditional solid slab. Primary advantage of voided slab is lighter than conventional solid slab, as a result of it, studies have done on capacity analysis of voided slabs. In the paper, four node tetrahedron finite element slab model was analysed. Nonlinearities of concrete and reinforcement bars was incorporated in the numerical programme using stress-strain relationship of each material. Numerical load-deflection plot was compared with experimental plot. Experimental and numerical results are matched appropriately in terms of ultimate load and deflection but not in first crack location. A parametric study was performed to study the impact of change of grade of concrete on the deflection and ultimate load. Numerical findings were shown. Results obtained from the numerical analysis showed that grade change of concrete will not significantly affect the ultimate load and deflection.
