Concrete Design and Technology (CVEN90016)

AIMS

This subject introduces the students to advanced modelling techniques for concrete structures, and to the design and analysis of pre-stressed concrete structures with applications to both buildings and bridges. It builds on knowledge from CVEN90049 Structural Theory and Design 2, in particular the section on the fundamental behaviour of reinforced concrete structural elements when subjected to flexure, axial load and shear. Students will be introduced to strut-and-tie modelling which is used in the analysis and design of complex regions in concrete elements where simple flexural behaviour is disrupted, and also to deformation modelling for reinforced concrete elements which highlights the importance of ductility in these elements. This subject will also introduce advanced concrete technology with discussion of high strength concrete, deterioration mechanisms and the design for durable concrete structures. Students who complete this specialist subject are likely to find employment in design consultancy or concrete construction companies and work under the supervision of a senior engineer.
