Course description and aims

This course focuses on the fundamental mechanical behavior of structural concrete, which holds the important role in civil engineering structures, such as concrete bridges. In addition, to prevent the brittle failure of structural concrete, the basics of shear failure are also explained. Specifically, each student is required to be able to calculate the following items: (1) flexural cracking capacity of a reinforced concrete member subjected to bending moment, (2) flexural capacity of a reinforced concrete member subjected to bending moment or bending moment and axial force, (3) flexural cracking width of a reinforced concrete member subjected to bending moment, and (4) shear capacity of a reinforced concrete member subjected to shear force. Although these contents are quite fundamental for the structural concrete, they are strongly required practically. It is expected for each student to fully understand the contents of this course.

Student learning outcomes

By the end of this course, each student will be able to:
(1) calculate the flexural cracking capacity of a reinforced concrete member subjected to bending moment.
(2) calculate the flexural capacity of a reinforced concrete member subjected to bending moment or bending moment and axial force.
(3) calculate the flexural cracking width of a reinforced concrete member subjected to bending moment.
(4) calculate the shear capacity of a reinforced concrete member subjected to shear force.

Keywords

reinforced concrete, flexural cracking, flexural failure, flexural moment and axial force, shear failure

Competencies that will be developed

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

Class flow

To confirm whether the students have understood the contents of each class or not, some assignment will be given occasionally. When the class of "pure flexure" is finished, the midterm exam will be done to check the acquisition of students whether they can understand the contents of classes. Final exam will be done for all of contents in this course. In the class, students will be asked by the instructor and need to answer to these questions.
