This work aims to study the crack pattern in masonry-like structures by a simplified description of the medium using a variational damage model. In literature, when modeling fractures in masonry structures, capturing both fracture types, cracks in units, and cracks at the interface simultaneously, usually requires a complicated scheme.

Timely monitoring the large-scale civil structure is a tedious task demanding expert experience and significant economic resources. Towards a smart monitoring system, this study proposes a hybrid deep learning algorithm aiming for structural damage detection tasks, which not only reduces required resources, including computational complexity, data storage but also has the capability to deal with different damage levels.

Strengthening of reinforced concrete (RC) columns is needed when the actual load-carrying capacity of the columns does not reach the required level due to either structural deterioration or increasing acting loads. This experimental study aims to evaluate the strengthening effect on the eccentrically-compressed RC columns using Carbon fiber reinforced polymer (CFRP) sheets, that confine around the column cross-section.

This paper develops a three-stage framework to simplify the process of efficient deployment of ITS application services in a specific city. Three stages include identifying potential ITS services, evaluating and ranking the priority of ITS application services, and analyzing legal requirements as well identifying any gaps or areas where the current legal framework may fall short in accommodating ITS technologies.

Output-only methods based on machine/deep-learning algorithms are highly practical approaches for timely detecting potential damages in civil structures as they directly employ measured vibration signals but do not require exact knowledge of input loading nor the service interruption for manual inspection.

The implementation duration of road work is critical as it impacts both the cost and outcome of the project. The article examines the techniques used to determine the time required for the completion of road work projects. It explores the approach to estimating the duration of road work projects in low- and middle-income countries (LMICs) based on the ROCKS database created by the World Bank.

This thesis presents a pro–active research work motivated by the prospect of the imminent implementation of the regulatory requirement for pedestrian protection, Global Technical Regulation–9 (GTR–9) (United Nations Economic Commission for Europe 1998) in the near future. To meet the performance criteria for pedestrian protection head impact, it is vital to incorporate the required design parameters into the hood design process at an early stage. These main design parameters are architectural and changing them late in the vehicle design process is very expensive and difficult to implement.

This research focuses on Fibre Cement Felts (FCF), which is a non-woven textile substrate acting as a conveyor belt for the manufacturing of Fibre Cement Sheets (FCS). Fibre Cement Felts are a valued component required in the manufacturing process of Fibre Cement Sheets, used in construction for today’s building industry. Identifying the key factors that most influence FCF will assist in understanding of the relationship between fibre diameters, carded web, and mechanical bonding.

The objective of this thesis was to investigate the development of a micro-electromechanical system (MEMS) which can be implanted in the eye to provide continuous monitoring of glaucoma conditions. Current glaucoma monitoring involves taking laboratory based intra ocular pressure (IOP) measurements. The measurement of intraocular fluid flow and IOP parameters related to blockage formation in the eye require to be continuously monitored in Glaucoma.

Housing is an essential amenity. However the impact, due to current trend of increasing embodied energy consumption per capita should be minimised. This may even require major cultural shift to traditional construction processes, practices and home owner perceptions. This thesis presents the outcomes of a study investigating ways to produce a “bill of embodied energy” for housing sector aligned to the standard practice of “bill of quantities”.

The main aim of this study is to investigate utilising root-like architectures to improve the interfacial strength of pin-integrated hybrid composite-metal structures. Joints are critical elements in aircraft structures and require special consideration due to their vital role in the structural integrity of airframes. Although bonded and bolted systems are used commonly in engineering applications, pinning technologies have shown tremendous potential for hybrid joints.
