I've got to agree with slickdeals. The Seismic Design Handbook is excellent. The 2nd edition (which is the one I have was published in 2001).
It has chapters on the following fundamental concepts:
1) The nature of earthquake motion
2) Response Spectra
3) Geotech Issues (Soil effects, liquifaction...)
4) Dynamic response of structures
4) Equivalent Static Force Procedures (1997 UBC and 2000IBC)
5) Drift and stability
It also has detailed chapters on the seismic design and detailing of
1) Diaphragms
2) Steel Structues
3) Reinforced Concrete
4) Wood and Masonry
5) Non-Structural components
6) Architectural Considerations
It's got a number of chapters on more advanced topics (Base Isolation, Performance Based Design Procedures, et cetera).
I swear that I'm not related to Farzad Naeim (or any of the other authors), I just think it is a very good reference for a wide variety of seismic topics.
