Risk CDT - Reinforced Concrete Response to Near Field Explosions
PLEASE APPLY ONLINE TO THE SCHOOL OF ENGINEERING, PROVIDING THE PROJECT TITLE, NAME OF THE PRIMARY SUPERVISOR AND SELECT THE PROGRAMME CODE "EGPR" (PHD - SCHOOL OF ENGINEERING)
This is a project within the multi-disciplinary EPSRC and ESRC Centre for Doctoral Training (CDT) on Quantification and Management of Risk & Uncertainty in Complex Systems & Environments, within the Institute for Risk and Uncertainty. The studentship is granted for 4 years and includes, in the first year, a Master in Decision Making under Risk & Uncertainty. The project includes extensive collaboration with prime industry to build an optimal basis for employability.
The project will involve an investigation of the behavior of reinforced concrete (RC) elements exposed to air-blast explosions from different explosive masses detonated at close-range. Through the validation of the numerical models with existing (and potential) experimental data, a reliable numerical model will be developed to predict 1) the local damage (i.e. spall and breach) and 2) global response of the RC element. This study will involve a modelling parameter reliability analysis which aims to populate a robust database comprising different charge weights, charge locations, and concrete and reinforcement properties for use in reducing the risk and uncertainty in protective structural design.
The fundamental objectives of this project are to:
Accurately predict the extent of damage depending on the scaled distance
• Determine failure modes (local and global)
• Investigate the relationships among local damage, reinforcement configuration and ratio, concrete compressive strength, state of the core of the RC element, and residual capacity of the RC element
• Investigate the differences in deflections along the height of the RC element
The results of this project will be used to provide comprehensive design recommendations to industry which enable practicing engineers to adopt an alternative analysis approach with due consideration to uncertainty quantification and modelling parameter reliability which is very important when field testing is not feasible.
The PhD Studentship (Tuition fees + stipend of £14,296 annually over 4 years) is available for Home/EU students. In addition, a budget for use in own responsibility will be provided.
