The optimization of a 3D printed concrete column to match the performance of a conventional cast in-situ un-reinforced concrete column

Abstract

As technology evolves and everyday requirements change with the need for more complex and intricate structures, innovative design and construction methods are found. One way to keep up with this demand was the adoption of three-dimensional printing (3DP) which has been used widely in many commercial sectors. This however has not been implemented in the same way when it comes to the design and building of structures in the architectural industry. The aim of this study is to realise the possibility of optimizing the structural performance of a three-dimensional concrete printing (3DCP) column with a particular focus on the use of different in-fill patterns. Through research of various available in-fill patterns, the design of modified in-fill patterns was undertaken. This study focuses on the structural simulation of digital models of these innovative patterns rather than physically printed models due to the lack of availability of a concrete 3D printer locally up until this dissertation was written. Through the use of 3D modelling software as well as Finite Element Analysis (FEA), this study delves into the possibility of achieving a better performing 3DCP column as well as a comparison of the best performing 3DCP column to a conventional cast in-situ concrete column. The relevant importance is given to the results achieved through the simulation process however it is worth noting that this dissertation provides a holistic understanding of the complete design procedure from the initial line drawing up to the finished digital model to be tested. Therefore, a particular focus is given to the methodology undertaken throughout the study which realizes the advantages, disadvantages and alternative routes taken in this methodology as well as areas for further research in implementing the simulation and possibly the manufacturing of optimized 3DCP structures.
