Desempenho do concreto e do aço no sitema de laje pré-fabricada e BubbleDeck

Abstract

The research for new solutions increasingly viable in an economic and productive way for slab systems of reinforced concrete led to the study of a combination of pre-fabricated lattice panels and the BubbleDeck technology. To the benefits of this system to be fully obtained, it is important that occur a project where the constituent materials to be maximized in a way that reduce the waste, but without abdicate security. With this goal, the present work consists in a behavioural analysis of the concrete and steel in the element that acts more effectively in its structural resistance, which is the pre-fabricated lattice panel. The analysis was made by means of the elaboration of spreadsheets that give, in a numeric and graphic way, the theoretical values of the internal forces and deflection of the structural element with different cross sections and subject to a loading condition. A case study of a laboratory test was used as a way to compare the results, as the values found by the use of the structural analysis program Robot. In this way, it was possible to obtain as result the influence limits of the materials concrete and steel in the resistance of the system of pre-fabricated lattice panel and BubbleDeck, as well as to predict its behaviour when subject to a loading.
