Building Science and Construction Innovation Team

The Building Science and Construction group, led by the Head of Civil Engineering, Professor Hong Guan, is currently undertaking research involving conducting a series of flat plate substructure tests to failure. This ARC Discovery project research will ultimately improve the integrity, robustness and safety of concrete flat plate systems.

Multiple hazards, such as earthquake, wind, fire and progressive collapse triggered by accidental local failure, impose enormous technical challenges to building structures throughout their service lives. With rapid development of construction materials and innovative techniques, the load-carrying mechanisms and structural performance against various loadings are being investigated at Griffith on a wide range of construction systems and structural types, including concrete flat plate structures, cold-formed steel structural members, aluminium structural members and tall timber structures. Large-scale experimental testing facilities have been developed and numerical simulation approaches have also been established for these investigations. Based on our research outcomes, relevant design guidelines and recommendations will also be derived.

All these research projects will ultimately improve the integrity, robustness and safety of various building structures popularly used in construction industry. Ultimately relevant design standards will be enhanced so that injury and loss of life can be prevented in both new and existing buildings.

Concrete Flat Plate Systems

At the School of Engineering and Built Environment, a group of academics and HDR scholars led by Professor Hong Guan has conducted a series of concrete flat plate substructure tests to failure, funded by an ARC Discovery Project. Reinforced concrete flat plate systems are popularly used in the construction of modern day high-rise buildings in Australia and internationally. There are potential risks of progressive collapse, which is characterised by a disproportionate and catastrophic collapse of the structure due to a sudden removal or failure of a major vertical load-carrying component caused by explosions, bomb blasts or natural disasters. However progressive collapse of flat plates is still one of the most under-researched areas and no proper guidelines to design such a structure to resist progressive collapse are available.


The group  investigated the load carrying mechanisms, force redistribution patterns and large-deformation behaviour of the substructures under various column loss scenarios. Some test results have already been accepted for publication in the Journal of Structural Engineering, American Society of Civil Engineers. Numerical simulation method is also developed to enable further investigations of the failure mechanisms of the structure which are not easily obtainable from the laboratory tests. Numerical parametric studies of the characteristic design factors will be carried out subsequently, through which a set of design recommendations
can be derived.

Through this study, design standards will be enhanced so that injury and loss of life can be prevented in both new and
existing buildings.
