On The Non-Linear Finite Element Modelling of Self-Compacting Concrete Beams

Abstract

Self-Compacting Concrete (SCC) is a form of concrete that is able to compact itself under its own weight. Many experimental researchers have resorted to trying to understand the behavioural properties of SCC used in structural elements such as beams. Nonetheless, the validation of the responses of small-scale components using finite element analysis can help engineers to parametrically characterise the behaviour of large-scale components. This study proposes a finite element model to analyse two different SCC beams by using the computational platform, ABAQUS. The load-deflection curves of tested beams was primarily used for verification purposes, with theoretical code-based estimates serving as benchmark. Results indicated that the FEM model compared very well with the experimental responses observed in terms of deformation and load capacities at first crack and ultimate failure. The absolute error in the responses for the developed finite element model was on the average 2.3% and 7.8% for the ultimate failure loads and deflections respectively.
