34.11.4. Nonlinear Analysis Requirements

Try these first

1. 1.

   What is pushover analysis?

   Hint

   Think about how structures react to static loads.

2. 2.

   Why do we perform time-history analysis?

   Hint

   Consider the dynamics of an earthquake.

3. 3.

   What is the primary goal of pushover analysis?

   • To predict lateral loads
   • To determine failure points
   • To assess ground conditions

   Hint

   Think about what you're trying to find out when pushing a structure to its limits.

4. 4.

   True or False: Time-history analysis can reflect real earthquake motions.

   • True
   • False

   Hint

   Consider whether this analysis mirrors actual conditions.

5. 5.

   A retrofitted building using pushover analysis shows no failure until a lateral load of 200 kN is applied. If the building experiences an unexpected seismic load of 300 kN, what implications does this analysis have for building safety?

   Hint

   Consider real-world implications of the pushover test results.

6. 6.

   Using time-history analysis, a building responds to an earthquake simulation in a way that exceeds expected displacements. List factors that might influence this response.

   Hint

   Think about the components that contribute to building performance under load.
