Avaliação do efeito da punção em lajes pré-moldadas localizadas em pavimentos garagens

Abstract

This work aims to analyze the punching phenomenon in precast slabs in garages, considering the concentrated and distributed loads defined by the ABNT NBR 6120 (2019) standard. Puncture analysis is extremely important to ensure the safety of using these slabs in garage structures, where sustaining loads and concentration of forces occur in certain regions close to pillars and supports. During the study, the effects of the applied load concentrated on the compression slab, that is, the cover of precast slabs, will be investigated, considering both concentrated loads and uniformly distributed overloads. The feasibility of using precast slabs in garages will be evaluated based on the results of the puncture analysis. A comparison of the results will be made with the safety requirements established by the norms and guidelines of structural projects, as well as the needs of the garages in terms of load and use. At the end of the study, it is expected to provide recommendations and practical guidelines for the safe and efficient application of precast slabs in garage projects, in addition to providing a better understanding of the considerations involved in the use of this type of slab in garages, ensuring safety. and the good performance of the built structures.
