RESUMO O sistema de lajes lisas com vazios oferece uma série de vantagens que justificam sua aplicação em diversasconstruções. No entanto, devido à ausência de vigas, requer análises detalhadas em relação à falha por punção. Nesteestudo, é apresentada uma simulação numérica de uma laje com vazios esféricos utilizando resultados de um programaexperimental disponível na literatura. A modelagem foi conduzida empregando o Método dos Elementos Finitosatravés do software ANSYS, visando determinar deslocamentos e deformações na estrutura. Com base nos dadosobtidos, foi possível identificar que a simulação reproduziu a falha por punção adequadamente, demonstrando umaboa concordância com os resultados experimentais.ABSTRACT The system of flat slabs with voids presents a series of advantages that justify its application in various constructions.However, due to the absence of beams, an in-depth analysis regarding punching shear failure is required. This studypresents a numerical simulation a slab with spherical voids using results from an experimental program available inthe literature. Finite Element Method modeling was employed using the ANSYS software to determine displacementsand deformations in the structure. Based on the numerical data, it was possible to identify that the simulation exhibitedpunching shear failure and achieved a good approximation to experimental results.
