Teaching Method

Outline:

A professor of this subject has an experience as an engineer of bridge fabricator. He engaged in design of steel bridges and steel structures. Based on his experiences, he will explain outline of steel and concrete structures as the knowledge to design structures and he will teach outline of design methods. Also, he explains mechanics fundamentals required for the design of structures, application method of design load to the girder, design internal force calculation of the girder, verification method of the load carrying capacity, and design method of members subjected to axial force so that students can understand specific design procedure of structure.

Style:

This subject will be explained concerning outline of structures, main design methods and design standards, design load for the steel bridge, its application method, section force calculation method using influence line for the bridge design, verification method of the load carrying capacity and design method of the member subjected to axial force by lecture-style.

Notice:

This class will be proceeded on the premise that students have learned fundamental knowledge of structural mechanics, construction materials and concrete structures. This subject has a content the summation of learning time guaranteed in class and standard self-learning time including required time for conducting preparation, review, and assignment corresponds 90 hours.
Students who miss 1/4 or more of classes will not be eligible for evaluation.
