Endurance Time (ET) Method
The Endurance Time (ET) method is a seismic structural analysis method utilizing intensifying dynamic loads. As the intensity of excitation is increased, the structural response is monitored. Structural performance is evaluated based on the response as a function of the excitation intensity.
Endurance Time Excitation Functions (ETEFs)
A classification of the ETEFs are presented in the following table:
