Teaching Method

Outline:
Steel is one of the indispensable material to construct infrastructures. Steel has been applied to many structures while improving the properties and also it is expected that steel will be applied to renewal and new construction of structures by improving performance and enhancing functionality in the future. Therefore, fundamental knowledge of steel structures is indispensable for engineer committing plan, design, construction and maintenance of infrastructure. In this subject, a teacher, who has an experience as an engineer of bridge fabricator and has engaged in design of steel bridges and steel structures, will conduct lecture-style class on mainly characteristics of steel and load carrying capacity evaluation of steel members , so that students can learn fundamental knowledge required for design, fabrication, erection, maintenance and repair of steel structures, based on his experiences.
Style:
This subject is conducted lecture-style class and also the design example of a steel member is shown and explained in the class. This will be helpful for students to be able to deepen their understanding of action in design of steel structures and evaluation method of the load carrying capacity. During class, in order to grasp the understanding of each student, teacher may proceed with the class while asking the student questions with regard to structural mechanics and contents which have already been learned in this subject.
Notice:
This class will be proceeded on the premise that students have learned fundamental knowledge of structural mechanics. Stress and its limit value required for designing steel members and concept of the verification will be explained through design example of simple steel structure. Students do not miss the review of the lecture, and try to be able to calculate the stress and limit values of the steel members explained during the class.
If the number of absences exceeds more than 33% of total school hours, pass is not accepted.
