Course description and aims
This lecture will cover the seismic design of nonstructural components, especially ceilings, which are feared to cause serious damage to human lives and business continuity of society in the event of an earthquake. Non-structural components of buildings include exterior walls, ceilings, partition walls and other finishing materials, furniture and other fixtures, and equipment. This lecture will introduce examples of fall damage that occurred in past earthquakes and explain how to deal with each cause of damage.
Damage to nonstructural components caused by earthquakes is a problem not only in Japan but also in other earthquake-prone countries. This is because research on structural frames has led to improved seismic performance, while research on nonstructural components has been insufficient. The basic concept of seismic design is the same as that of structural frames, but nonstructural members exhibit brittle behavior and require countermeasures against acceleration and relative displacement. It is also necessary to consider that seismic motions are amplified by the vibration of the structural frame, and that the amplified shaking becomes an input to nonstructural components.
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) Explain the characteristics of the seismic response of structural frames
3) Calculate inertia force acts on non-structural components in earthquakes
4) Find methods to mitigate seismic damage of non-structural components
