In this course, four different experiments will be done to enhance students' understanding of fundamentals of structural mechanics. Students conduct tensile tests of steel, buckling tests, bending tests on a beam and vibration tests on a beam. In tensile tests, students will prepare for the tests and observe the fracture behaviors. In bridge competition, students will design and make a model bridge under a given condition, and compete the performance of the model bridge. In the bending tests and vibration tests on a beam, students will prepare an experimental plan, and discuss the fundamental theory based on the obtained experimental results. In buckling tests, students will observe the buckling behaviors of a number of specimens and discuss the results by comparing the theory and experiments.
Understand the fundamentals of structural mechanics and the fracture behaviors of structures.
Enhance the ability to conduct given tasks independently and creatively through group work on the planning of experiments and on the design of model bridges.

Performance of students will be evaluated by submitted reports (100%).
If a student is absent from the class without any contact once, he/she cannot get the credit for this class.
If the preparation for the experiments is not enough, a student may not attend the experiment.
