Question 1.
What does SDOF stand for?
Show hintHide hint
Think of how many movements it accounts for.
Question 2.
Why can't SDOF models predict localized deformations?
Show hintHide hint
What is the primary focus of SDOF models?
3Question 3.
What is a major limitation of SDOF systems in relation to seismic analysis?
- They account for all types of motion
- They do not capture multi-modal responses
- They include detailed local failures
Show hintHide hint
Consider what happens during an earthquake in complex buildings.
4Question 4.
True or False: SDOF idealizations can effectively predict localized deformations in a structure.
- True
- False
Show hintHide hint
Think about what SDOF models focus on.
Question 5.
Discuss and exemplify the impact of ignoring torsional effects in the design of an L-shaped building during an earthquake.
Show hintHide hint
Reflect on how asymmetrical shapes can behave differently under seismic forces.
Question 6.
Analyze how subsequent building codes began to address the shortcomings of SDOF in seismic assessments. Provide examples.
Show hintHide hint
Consider how standards must adapt to reality in engineering.
