Structural Performance of Load-Bearing 3D Printed Walls Using Reinforcement methods (Advert Reference: RDF20/EE/MCE/HACKNEY)


Project Description

In the last few years, 3D printing technologies are attracting a growing interest in the construction industry because of its freedom in designing shapes, elements and complex structures without having any formwork. In 3D concrete printing, the main structure is manufactured in layers directly from a digital model and the material is then deposited at its final position. Hence, to some extent it could save wastage of materials, construction time and the manpower required in the construction site.

This research project deals with the structural performance of 3D printed load-bearing walls with directly entrained metal cable as reinforcement. Several options for reinforcement at varying positions and configurations will be compared in terms of printability and structural strength. Subsequently, pull-out tests on cast and printed specimens will provide its bond behaviour. Furthermore, bending and compression tests will indicate the potential of the reinforcement configuration. In addition, an advanced finite element model will be carried out to investigate the structural performance of the load-bearing walls. The approach is expected to facilitate the production of free-form improved load-bearing wall structures with the final aim of saving concrete material and, at the same time, fabricating lighter structures.

This principal supervisor for this project is Associate Professor Phil Hackney. Other members of the supervision team will include Dr Keerthan Poologanthan, Dr Brabha Nagaratnam and A/Prof Alan Richardson.
