About the Project

Our futuristic vision for Sustainable and Resilient Structures is one that has transparent expectations of structural performance against time, increased loads, environmental changes and natural disasters. Our goal is to adapt quickly to new circumstances and prepare for future and uncertain threats. Under extreme single or multi-hazardous events, such as earthquakes and fire, the safety margins of structures can be exhausted quickly. The sudden failure of individual components and their uncontrolled interaction with the adjacent elements can trigger significant structural instabilities in both local and global level thus leading the structure to unexpected partial or total collapse.

This project aims to investigate the behaviour of concrete-filled steel tubular (CFT) columns under post-earthquake fire. CFT columns are cost-effective high-performance composite members that can effectively resist seismic loads offering a reduced weight compared to the corresponding all-steel tubular steel columns (best seismic performance with material economy). The earthquake-fire performance of such columns is still unexplored, and it is expected a significant improvement compared to conventional all-steel or all-concrete columns due to the combined benefits of both materials. The project will perform both experimental and computational research with focus on the development of new multi-hazard design guidance for composite columns.

PhD qualifications:

Prospective students should hold at least a 2:1 Bachelors degree (or equivalent GPA from non-UK universities) or a Masters degree (preference for Merit or above) in a relevant technical subject. The project is well suited to motivated and hard-working candidates with a keen interest in Structural Engineering and Composite Structures. A basic knowledge of finite element analysis methods (e.g., ABAQUS, ANSYS) and programming languages (e.g., MATLAB or Python) is essential. Basic understanding/experience of laboratory procedures and experiments are desirable.
