Resumen:

This paper develops simple expressions to estimate plastic energy demands for soft soil sites (particularly, those located in Mexico City), capable of generating long duration narrow-banded ground motions. To overcome the limited scope of previous studies, about 35,000 seismic simulations were performed using two scaling methodologies (linear and seismological). A new simplified relation between plastic hysteretic energy and maximum ductility demands is presented, and a discussion offered on how it can be used to allow for an energy-based design aimed at controlling structural damage under the explicit consideration of low cycle fatigue. © 2018 11th National Conference on Earthquake Engineering 2018, NCEE 2018: Integrating Science, Engineering, and Policy.
