Inovação na construção civil: proposta de melhoria no processo da concepção estrutural de um edifício no dimensionamento à punção de lajes lisas protendidas com cordoalhas não aderentes

Abstract

The civil construction industry is a relevant sector for the national economy, and its technological advance is due to the way in which public and Science, Technology and Innovation (S,T&I) policies are developed and implemented. The structural model with prestressed flat slabs is an example of technological advancement, however this structural model presents the possibility of punching failure which, despite the subject having already been widely researched, can still lead to the general collapse of the building structure. Analyzing the legal context and the practical application, this work aimed to develop a computational platform to be used by the civil construction industry that uses the normative prescriptions of ABNT NBR and that generates an improvement in the process that culminates in the occurrence of punching rupture in prestressed slabs. In order to achieve the objectives, a research was carried out with an explanatory objective and a qualitative approach with the intention of raising the theoretical reference regarding the punch and the Brazilian public policies of S,T&I. Then, the calculation routines and flowcharts for the development of the platform were developed. In the end, the work suggests an improvement in the process with the addition of MGDCALC, an application that performs the dimensioning to punch in prestressed flat slabs, in addition to indicating ways for the transfer of technology to occur.
