Punção em laje lisa – teoria e cálculo de armadura: material didático para o auto aprendizado.

Abstract

The calculation and structural design are subject to a wide range of solutions. One commonly adopted solution is the use of a solid flat slab without the presence of beams, with specific reinforcement to resist the punching shear forces that arise for this type of slab. The punching shear effect on the slab can be understood as the concentrated shear force around the column due to the absence of beams, which also assist in distributing the load from the slabs to the columns. In this effect, the column tends to "punch through" the slab, requiring punching shear reinforcement to resist these forces, which can lead any structure under this effect to collapse. This work emphasizes these structures, using the ABNT NBR6118:2023 standard to design slabs for punching shear through calculation routines developed to facilitate the use and understanding of the subject. The products of this work, which are the monograph itself and the calculation and verification routines created with the aid of software, constitute educational materials to be used for the teaching and learning process of the subject.
