Energy Based Seismic Assessment of Degrading Systems

Modern seismic design philosophy states that
buildings should be designed not only for life safety
but also for damage control. To accomplish these dual
objectives, design guidelines have been revised to
construct structures with predictable seismic
performance. Structural damage under seismic loading
is dependent on many factors as maximum displacement,
dissipated energy during seismic response, number of
yield excursions and low-cycle fatigue. The complex
damage behavior of structural systems subjected to
ground motions can only be assessed when all of these
factors are considered interactively. This book
focuses on the assessment of energy dissipation
characteristics of structural systems through
experimental low-cycle fatigue data. Based on these
findings, an energy-based hysteresis and a damage
model are developed. These models are then used to
predict the seismic damage when structural systems
are exposed to actual ground motions. The simple
procedure introduced at the end of the book is deemed
to be a guideline for the structural engineers and
academicians who have been experiencing a new era in
seismic design philosophy: performance-based
engineering.
