Summary

This course will focus on advanced behavioural modelling of reinforced concrete through analytical and numerical methods. It will build on previous studies to further the student's understanding of the mechanics of reinforced concrete at the material, element, and structure level.

Content

Introduction and review of mechanics of reinforced concrete
Mechanical properties of concrete, steel, and crack interfaces
Linear and nonlinear models for plain concrete
Failure criteria for plain concrete
Modelling of planar, cracked reinforced concrete
Nonlinear finite element implementation
The Modified Compression Field Theory
Pre-strains and plastic offsets
Advanced behaviour modelling (dowel action, bond, etc.)
Extension to member-level behaviour and design codes
Comparison of linear vs. nonlinear analysis
Case studies of nonlinear finite element analysis

Learning Outcomes

By the end of the course, the student must be able to:

• Describe the mechanical properties of concrete, steel, and crack interfaces
• Make calculations of concrete stress tensors from given strain tensors for different models
• Explain the differences between different types of models for cracked reinforced concrete (i.e. fixed/rotating crack; smeared/discrete crack)
• Formulate and iteratively solve nonlinear 2D stress/strain states
• Use nonlinear finite element analysis software to model reinforced concrete structures
• Identify potential shortcomings in using linear analysis for design
