Non-Flood-Related Hazards: Seismic (2 of 4)

Seismic forces at a point on a building are a function of:

  • Weight
  • Soil type
  • Height
  • Distribution of weight (mass)
  • Type of building frame
Effect of seismic forces diagram on 3 buildings. 1. Ground movement due to earthquake. 2. Design assumptions based on building code. Lateral forces transferred to and resisted by designed walls or primary resisting frame. 3. Effect of tension and compression on foundation due to moment created by overturning.
