Reflecting the major expansion and revision of requirements for seismic design contained in the 1988 Uniform Building Code (UBC), this 2nd edition has been expanded to cover a wider range of building types and situations and include more discussion of general building design issues. There is also considerable new material on design of foundations for lateral loads. Emphasis throughout is on design fundamentals for minimizing wind and seismic effects on buildings. Discussion of current directions in research, experiences from recent major disasters, and developments in design by leading professionals in the field is included and a new section contains study materials.
