Time History Development

Two factors that should consider when selecting time histories?

• Location and Intensity

• Magnitude and Intensity

• Magnitude and Distance

• Distance and Location

It is needed for analyzing dynamic responses of nonlinear structural systems, such as site response or structural analysis.

• Time history scaling

• Earthquake time histories

• Time history analysis

• Selecting time histories

Involves a time domain modification of an acceleration time history to make it compatible with a user-specified target spectrum.

• Time history scaling

• Time history analysis

• Spectral matching

• Selecting time histories

What percentage of tolerance is fine when developing 3 sets or less of time histories?

• 10-15%

• 15-30%

• 30-45%

• 45-60%

What percentage of tolerance is fine when developing 7 sets of time histories?

• 10-20%

• 20-30%

• 30-40%

• 40-50%

What are the two methods used to get the time histories to match the design spectrum?

• Time history and time analysis

• Spectral scaling and  selecting time histories

• Time history scaling and spectral matching

• Time analysis and selecting time histories.

It involves modifying a time history's scale and time step in order to try to closely match the design response spectrum.
