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.
Partially prestressed concrete beams: Properties of prestressing steel and types of prestressing systems; Sectional behaviour at service load level, equivalent load concept and load balancing; Creep and shrinkage in concrete; Estimation of prestress losses, deflection and amount of cracking; Indeterminate structures; Anchorages; Applications to building and bridge construction; Applications to precast concrete structures; Deformation modelling; Strut-and-tie modelling; High strength concrete; Design against physical and chemical attack of concrete structures.
Intended learning outcomes
On completion of this subject the student is expected to:
- ILO 1. Use advanced deformation modelling techniques and tools for modelling concrete structures
- ILO 2. Use strut and tie design methodology to design non-flexural members such as deep beams
- ILO 3. Describe the technology related to high strength concrete and demonstrate awareness of the important factors affecting its performance in practical applications
- ILO 4. Design against physical and chemical attack of concrete structures
- ILO 5. Describe the behaviour of partially pre-stressed concrete beams, and analyse and design these structures. The implementation of measures to improve environmental sustainability will be discussed in relation to design
