SIL = Seismic Intensity Level

WHAT : Seismic Intensity Level (SIL)?

In modern seismic design and technology, buildings are designed with earthquake resistance in mind. However, human casualties often result from the collapse of ceilings, bookshelves, and appliances. While buildings constructed under the latest seismic standards exhibit good earthquake resistance, they do not fully prevent human injuries.

The Seismic Intensity Level (SIL) is a scale used to measure shaking intensity based on human perception of earthquake. This intensity varies with the distance from the epicenter and local ground conditions.

SIL can serve as a valuable quantitative evaluation tool in seismic evaluation decision-making. It adds a quantitative "comfort" assessment, offering insights into how strong earthquake shaking impacts human lives within a building.

  QSEERB ( = IoT + SIL ) introduces comfort-based criteria to evaluate the seismic performances of buildings quantitatively.
