Adaptive Base Isolation using Innovative Magnetorheological Elastomers. Base isolation is of great importance for the safety of infrastructure, such as hospitals, bridges and nuclear power plants. Utilisation of a traditional passive base isolator makes the base isolation system vulnerable and susceptible to unexpected/extreme dynamic loadings, such as earthquakes. This project aims to address this critical issue through the development of a novel adaptive seismic isolator working with an innova ....Adaptive Base Isolation using Innovative Magnetorheological Elastomers. Base isolation is of great importance for the safety of infrastructure, such as hospitals, bridges and nuclear power plants. Utilisation of a traditional passive base isolator makes the base isolation system vulnerable and susceptible to unexpected/extreme dynamic loadings, such as earthquakes. This project aims to address this critical issue through the development of a novel adaptive seismic isolator working with an innovative stiffness softening magnetorheological elastomer (MRE). This research represents a fundamental step towards the understanding of MRE behaviour and is expected to be the breakthrough for the development of a future smart base isolation system.Read moreRead less
Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little ....Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little is known about the technology. This project will model the behaviour of rubber soil in order to introduce it as an environmentally sustainable, cost-effective and technically sound choice of geomaterial for both standard and non-standard geotechnical structures.Read moreRead less

New knowledge is expected to be generated on the novel use of polymer and concrete materials in hydrogen storage technologies. The expected outcomes include a new class of prefabricated, modular storage system that is highly efficient and low cost. The scalability and resilience of the system will be achieved by using concrete, a material widely used in the construction industry for its mechanical performance, durability and affordability. This should provide significant benefits in fostering the hydrogen economy by providing an efficient and resilient storage system for industrial quantities of hydrogen.Read moreRead less
Performance of safety critical anchors in early age concrete with SCM. This project aims to examine the performance of anchors in a range of cements, to contribute to new safety and building guidelines. Demands for faster construction cycles and increased productivity require anchors for lifting and joining concrete elements to be installed and loaded in early age concrete. Yet, best practice for evaluation of anchors is based on mature concrete. There is also increasing use of supplementary cem ....Performance of safety critical anchors in early age concrete with SCM. This project aims to examine the performance of anchors in a range of cements, to contribute to new safety and building guidelines. Demands for faster construction cycles and increased productivity require anchors for lifting and joining concrete elements to be installed and loaded in early age concrete. Yet, best practice for evaluation of anchors is based on mature concrete. There is also increasing use of supplementary cementitious materials with unknown effects on anchors. This project aims to address this construction industry challenge. The project plans to study experimentally and analytically the effect of early age creep on anchor installation and the factors affecting the slip behaviour and ultimate performance of cast-in and post-installed mechanical anchors in concretes. It is intended that these studies will then inform new design guidelines.Read moreRead less

This project aims to investigate the electro-mechanical behaviours of carbon nanotube reinforced polymer composite structures. Such structures demonstrate considerable potential in structural health monitoring and strengthening due to their unique electro-mechanical behaviours. However, the electro-mechanical behaviours of these composites remain unclear due to the multiscale nature of the problems and the constraint of current techniques to capture nanoscale features that underpin the macroscopic behaviours. This project aims to investigate the electro-mechanical behaviours of these composites and their structures via atomistic simulation and continuum mechanics modelling. The outcomes are intended to enhance the application of these multifunctional composites and improve the performances and sustainability of engineering structures.Read moreRead less

The project will explore the potential of new blended calcium-magnesium cements to significantly improve the sustainability and properties of concrete produced with Portland cement (PC). Concrete based on PC contributes to around 10% of global anthropogenic carbon dioxide. PC Concrete has many weaknesses such as rapid deterioration when exposed to aggressive environments, delayed reactions and early age cracking caused by shrinkage. The proposed research will investigate ways of using the new binder system to overcome these weaknesses and to reduce carbon dioxide emission. The expected outcome will be a proven technology for manufacturing new building materials that are environmentally more sustainable and with enhanced properties.Read moreRead less

This project proposes novel manufacture and analysis methods for fibre-reinforced polymer (FRP) hybrid sections. FRP composites have gained wide acceptance within the civil engineering community. All-FRP systems typically use thin-walled profiles based on steel sections, but existing manufacturing technologies are unable to optimise material usage. Hybrid systems combine FRP with traditional materials for optimum structural performance and so are often more economical than all-FRP systems. This project aims to develop an effective way to analyse, manufacture, and design FRP-based hybrid thin-walled structural members and optimise performance against buckling failure modes. The technology developed in this project would support the development of advanced low-cost FRP structural systems.Read moreRead less
