- ARC Linkage Project (2018-2020): Analysis and design of Interlocking Brick System against Earthquake Loading
Summary: This project aims to develop optimised interlocking bricks to resist static and earthquake loads. Using conventional bricks in masonry construction requires skilled labour to connect bricks with mortar. Development of interlocking bricks for mortarless connection has been attracting great interest because the easy alignment improves construction efficiency and quality. Interlocking also leads to better mechanical performance of the resulting structures. This project will have significant impact on construction technology and the Australian masonry industry, and greatly improve the competitiveness of the Australian construction industry in the international market.

- ARC Discovery Project (2019-2021): Improved analysis and design of structures to resist blast and impact
Summary: This project aims to develop an improved single-degree-of-freedom (SDOF) model which can be easily used in design analysis by engineers and yield accurate structural response predictions in analysis of structures subjected to blast and impact loads. Current practice uses SDOF models in analysis of structures subjected to blast and impact loads, however many experimental tests and high fidelity numerical simulations have revealed the current SDOF analysis approach does not always lead to accurate structural response predictions. This project will develop an improved SDOF model, which can be easily used in design analysis by engineers and yield accurate structural response predictions. These will lead to more economical designs and robust structures to resist blast and impact loads.

- ARC Discovery Project (2019-2021): Development of novel inerter-based damper for platform vibration control
Summary: This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable apparent mass that is much larger than its physical mass through an amplifying mechanism by translating the linear motion into high-speed rotational motion, which can significantly reduce the mass and cost of the damper. Benefits of the project include more economical and safer OFP designs, which are expected to improve the competitiveness of Australian pillar oil and gas industries.

- ARC Linkage Project (2017-2020): Bridge performance assessment through advanced sensing and modelling
Summary: This project aims to create cyber infrastructure to manage and maintain civil infrastructure, specifically bridges. Current sensor data interpretation approaches are not good at assessing the performance of civil infrastructure or evaluating the reserve capacity; in particular, they do not adequately account for high levels of systematic modelling uncertainties. This project intends to ease the current scientific data interpretation bottleneck. Expected outcomes are better infrastructure management and maintenance planning, fewer redundant interventions, modified infrastructure and improved future design.

- ARC Discovery Project (2016-2019): Development of Ambient Cured High Performance Fibre Reinforced Geopolymer Composite
Summary: Ambient cured high performance geopolymer composite. The project intends to develop an ambient-cured high-performance, sustainable, fibre-reinforced geopolymer composite for construction. Compared to cement, which is currently used extensively in the construction industry, production of the geopolymer material not only recycles industry wastes which would otherwise end up in landfills, but also consumes less energy and emits significantly less greenhouse gases into the atmosphere. The composite is also designed to have a higher strength and deformation ability than cementitious material. The project plans to perform intensive experimental tests to determine the optimal mix for the best performing material, and develop material and numerical models to predict the responses of structures made from the composite when subjected to static and dynamic loads.

- ARC DECRA Project (2015-2017): Using Sandwich Pipe for Pipeline Vibration Control
Summary: Pipelines are important lifeline structures but are vulnerable to different types of damages. These damages are often associated with pipeline vibrations. Therefore, it is important to control these adverse vibrations to reduce the possible catastrophic damages. This project proposes using sandwich pipe to suppress different sources of vibrations that may be experienced during the lifetime of the pipeline. Analytical, numerical and experimental investigations will be carried out to demonstrate the feasibility of the proposed method. The research results will find direct applications in designing of pipelines to suppress different sources of vibrations and to guarantee the safety of pipelines.

- ARC Linkage Project (2015-2018): An innovative light weight composite panel system for high speed modular construction
Summary: This project aims to develop an innovative composite panel system using aerated geopolymer and a thin high strength steel casing. The new panel system will have a number of significant enhancements compared to the traditional panels in terms of load resistance, much lower carbon footprint and life-cycle costs. It will offer desirable properties, such as being light-weight, easy to construct, economical, recyclable and reusable. A significant gap in knowledge exists in the material and system behaviour of the aerated geopolymer and its fire performance. A comprehensive research program will be carried out to address those challenges and to provide design guidelines to rapidly progress this technologies in Australia and overseas.

- ARC Discovery Project (2015-2018): Development of Precast Concrete Segmental Columns to Resist Dynamic Loads
Summary: Using precast segmental concrete columns in structures improves the construction efficiency and site safety, leads to better construction quality control, reduces the construction cost, site disruption and environmental impacts. The performance of segmental columns to resist earthquake and blast loads is not well studied yet. As a structure during its service life might subject to such loads, understanding its resistance capacities is essential for structural safety. This project will perform experimental and numerical investigations to study the performance of precast segmental concrete column under earthquake and blast loads, and develop analytical and design methods for applications of such columns in building and bridge structures.

- ARC Linkage Project (2015-2018): Study of blast resistance capacity of basalt fibre strengthened structures.
Summary: This project plans to investigate the dynamic response of basalt fibre reinforced polymer (BFRP) reinforced structures against blast loading. Critical infrastructures such as embassy buildings, high-rise building, bridges and defence facilities are intensively targeted by increasing terrorist activities or accidental explosions. BFRP is a promising material for such structures because it is cheaper than carbon fibre and has better physico-mechanical properties than glass fibre. However, there has been very limited study of the effectiveness of BFRP strengthening on structure blast-loading resistant capacities. This project aims to perform numerical and experimental studies to support the development of BFRP applications in strengthening structures against blast loads.

- CSIRO Flagship Project (2013-2016): Response and vulnerability modelling of structural facades and partition walls to resist windborne debris impact.
Summary: This project is to study of the performances of existing structural envelopes (e.g. structural insulated panels, fabric and masonry wall) against windborne debris impacts. The testing results can be used for the assessment of the application feasibility of different structural envelopes in cyclonic or non-cyclonic area. Fragility curves of structural panels, accounting for various uncertainties and random variations of the panel and debris parameters, are generated and used in loss predictions of building structures in extreme wind events. Possible strengthening techniques have also been investigated to increase the impact resistance capacities of the commonly used structural panels.
