11.20. Seismic Design Implications of MDOF Behavior

Try these first

1. 1.

   What does MDOF stand for?

   Hint

   Think about how many movements a structure can have.

2. 2.

   Define base shear in your own words.

   Hint

   Consider the force pushing a building laterally during an earthquake.

3. 3.

   What does MDOF stand for?

   • Multiple Degree of Freedom
   • Many Degrees of Force
   • Multiple Degrees of Failure

   Hint

   What does the acronym represent in structural analysis?

4. 4.

   Is base shear a critical component in seismic design?

   • True
   • False

   Hint

   Consider why forces acting on structures need to be calculated.

5. 5.

   Discuss the relationship between base shear and seismic design. What factors influence the calculation of base shear?

   Hint

   Consider the variables that affect a building's response during seismic events.

6. 6.

   Create a design approach for an MDOF system that incorporates multi-mode analysis. What steps would you take to execute this analysis?

   Hint

   Think about both the computational methods and the physical responses of the structure.
