Course description and aims

In this course, the instructor introduces nonlinear material models to describe the material behavior of concrete based on the hydration - micro structure development - mass transfer model, nonlinear structure models to describe the mechanical behavior of reinforced concrete based on the smeared crack model, and material-structure integrating model by coupling the aforementioned models.
In order to maintain the performance of reinforced concrete structures or design reinforced concrete structures more rationally, it is important to understand the structural behavior of reinforced concrete based on the characteristics of concrete material. The aim of this course is understanding the character of reinforced concrete through modeling.

Student learning outcomes

By the end of this course, students will be able to:
1) Explain the material behavior of concrete as porous material with the hydration-micro structure development- mass transfer integrated models.
2) Explain the mechanical behavior of the concrete based on smeared crack model.
3) Explain the impact of nano-micro meter scale material behavior on the structural behavior of structural system based on material-structure integrated model.


Reinforced concrete, Material-structure integrated analysis, hydration - micro structure development - mass transfer integrated model, smeared crack model, rheology model, deterioration

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

The final examination will be held at the end of the course. You are requested to submit a short report at the end of every class.
