Desenvolvimento de módulos computacionais para automatização do projeto estrutural de parede de concreto moldada in loco

Abstract

The goal of this work is to automate the process of analysis, sizing and detailing of the structural system of a concrete wall molded in loco. Automatization is performed based on a computational environment, created from the development and customization of computational modules. This structural system can be designed through different methodologies, however, the solution using numerical methods provides a series of positive points that collaborate for a better understanding of the phenomena with a good balance between time, cost and quality. In this context, the present work presents the development of a study focused on the main premises of the structural design of a concrete wall molded in loco, in order to promote the creation of an integrated computational environment. The environment is elaborated by customizing the interface of the commercial software ABAQUS/CAE®, integrating already existing computational modules that perform the modeling and structural analysis via the Finite Element Method with other modules that incorporate algorithms used in the sizing and detailing phases of the walls, based on the premises of NBR 16055 (2012). A concrete wall building of the program “Minha Casa Minha Vida” was used as a case study. The idea is that the study carried out in this work becomes useful to the technical-scientific environment, in order to contribute to the application of the design premises, based on an early stage prototype to assist in the elaboration of structural projects for a concrete wall molded in loco.
