Course description and aims

This course is the laboratory class focusing on the mechanics of the infrastructures, especially mechanical behavior of reinforced concrete and geotechnical structures.
In the classes on the reinforced concrete, students learn how a reinforced concrete structure is made and how they fail through the experimental work. And in the creative design competition, students get an experience of setting group goal and strategy to tackle a task, building consensus about them in the group, and overcoming technical challenging to achieve the group goal with integrating their knowledge and experiences.
In geotechnical engineering, theoretical solutions do not necessarily capture the actual behaviour of geotechnical structures. Therefore, it is important to know mechanical characteristics of soils and behaviour of geotechnical structures through experiments. The aim of this course is to obtain knowledge of mechanical properties of soil through conducting shear tests and to experience performance evaluation of shallow foundation through physical model test using geotechnical centrifuge.
This course aims to cultivate the basis of civil engineers through the experimental works. Students are expected to understand deeply the mechanical behaviour of reinforced concrete structures and geotechnical structures, and get an experience of the group management in engineering.

Student learning outcomes

By the end of this course, students will be able to:
1) Explain the fracture process of reinforced concrete members and the difference in failure pattern.
2) Explain the making process of reinforced concrete members.
3) Propose a group goal and strategy to tackle the task and build consensus for the group.
4) Implement the strategy to achieve the goal by integrating the knowledge about the property of cementitious material and structural design.
5) Understand the influences of void ratio and stress history on shear strength of soil.
6) Accumulate skill and knowledge for design of foundation through prediction of the bearing capacity of shallow foundation.

Keywords

Structural mechanics of reinforced concrete, Soil mechanics, Geotechnical structures

Competencies that will be developed

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

Class flow

Classes will be held in each separated group. Students should gather at the room where is instructed, and the understanding of the experiment contents and related matters are checked in advance of the experiment. Sometimes the understanding of the experiment is checked after the class. In every class, students are requested to submit reports.
