Abstract

3D MODELLING APPROACH FOR PRESTRESSED CONCRETE BRIDGES BUILT BY SUCCESSIVE CORBELLING BASED ON BUILDING INFORMATION MODELING (BIM) CONCEPTS.

ABSTRACT

Long span prestressed concrete bridges built by successive corbels are complex structures that require a collaborative platform such as the BIM to implement. Their modelling requires the use of various and complex software, very few of which are modular because they are based on fixed and approximate assumptions. Designing an interactive, efficient, iterative, iterative, accessible and adaptable digital model for all construction phases is the essence of this work. This model is of particular interest to construction companies because it provides the opportunity for real-time optimization. This article proposes a 3D modeling established via CASTEM software based on the theory of thin shells following Batoz's improved theory. This choice was validated by applying this method to the 2nd bridge over the Wouri. It is a key tool of the BIM platform that allows iterative optimization of the structure before, during and after construction.
