Assigned Department Objectives
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 outline of steel structures and bridges, recent digital transformation relating to steel structures, characteristics of steel and mechanics fundamentals regarding the design of steel structures, so that students can learn fundamental knowledge required for design, fabrication, erection, maintenance and repair of steel structures, based on his experiences.
Style:
In this subject, mechanics fundamentals required for designing steel structures will be explained by lecture-style class. The knowledge of mechanics fundamentals will be deepened through calculation examples. In addition, structural steel, classification, structure type and mechanism of the steel bridge will be explained in the class. Moreover, technologies for digital transformation of steel structures are introduced and practical exercise using them will be carried out. During class, professor may proceed with the class while asking the student questions regarding structural mechanics and contents which have already been learned in this subject in order to grasp the understanding of each student.
Notice:
This class will be proceeded on the premise that students have learned fundamental knowledge of structural mechanics. Mechanics fundamentals required for designing steel members will be explained through calculation examples regarding simple steel structures. Students do not miss the review of the lecture and try to be able to conduct mechanical calculation explained during the class.
Students who miss 1/3 or more of classes will not be eligible for evaluation.
