Course description and aims
This course covers non-structural elements that threaten to cause human damage and damage the continuation of society derived from extensive damage during an earthquake, and the nature of seismic design for ceilings in particular. Non-structural elements in architecture include finishing materials for outside walls, ceilings, and partitions, domestic items such as furniture, and facility equipment. Due to various vibration properties, in some cases acceleration causes damage, and in others displacement (story drift) causes damage. The instructor will present examples of damage from falling due in past earthquakes, as well as measures dependent on the factors causing damage.
Damage of non-structural elements in an earthquake is not just a problem for Japan, but also for countries where earthquakes occur. This is because research on structural frames has lead to improved seismic performance, while research on non-structural elements has been insufficient. The basic approach to seismic design is the same as with structural frames, however because non-structural elements display brittle behavior, it is necessary to take precautions against acceleration and displacement. The instructor will present computer-simulation and shaking table tests for students to get a sense of the danger of non-structural elements in an earthquake, and the importance of making them quake-resistant.
Student learning outcomes
By the end of this course, students will be able to:
1) Explain the reason why non-structural components suffered from damage in earthquakes
2) Calculate inertia force acts on non-structural components in earthquakes
3) Explain structural characteristics of non-structural components
4) Find methods to mitigate seismic damage of non-structural components

Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. Required learning should be completed outside of the classroom for review purposes.
