Tóm tắt

Shear failure of punching pertaining to slab of concrete reinforced type consisting of metal mesh expansion and lower density aggregates was simulated numerically in this study. We studied and spoke about the simulations' outcomes. Because punching shear failure occurs so suddenly and brittlely, research into it was crucial. Software of Finite element analysis (ANSYS V.2020.R1) was used for creating numerical models for punching shear failure of such slabs. Both non-linear performance of concrete and steel are considered for development of such prototypes. Modeled slabs applied solid components for concrete, space bars for reinforcements, a smear layer of embedded inside solidified elements for simulating an extended mesh of metal. Test information provided in concerned tasks were compiled by reviewing appropriate literature. Slab’s Numerical prototypes were tested, and their findings compared to published experimental data utilizing load deviation responses and pattern of fracture. There was excellent aligning between experimental outcome and findings of computer models. Predictions concerning the punching resistance of concrete slabs reinforced with expanded metal mesh and concrete slabs built with low density aggregate may be generated using the numerical models created for this work.
