Notes:
- Lessons from the Northridge Earthquake
- What did we learn from the Northridge Earthquake?
- After the 1994 Northridge Earthquake, the City of Los Angeles and Structural Engineers of Southern California formed a joint task force to re-evaluate several seismic provisions of the building code for wood frame buildings. The task force recommended significant changes to the design and construction of wood frame shear walls.
- The biggest lesson we learned was that materials did not do as well as we believed they would. We learned that we needed more material and wider walls.
- These changes included lowering the allowable height-to-width ratios and shear strength values.
