Abstract:
Displacement-Based Seismic Design of Structures is a book primarily directed towards practicing structural designers who are
interested in applying performance-based concepts to seismic
design. Since much of the material presented in the book has not
been published elsewhere, it will also be of considerable interest
to researchers, and to graduate and upper-level undergraduate
students of earthquake engineering who wish to develop a deeper understanding of how design can be used to control seismic
response.
The design philosophy is based on determination of the optimum
structural strength to achieve a given performance limit state,
related to a defined level of damage, under a specified level of seismic intensity. Emphasis is also placed on how this strength is distributed through the structure. This takes two forms: methods of
structural analysis and capacity design. It is shown that equilibrium considerations frequendy lead to a more advantageous distribution of strength than that resulting from stiffness considerations. Capacity design considerations have been re-examined, and
new and more realistic design approaches are presented to insure
against undesirable modes of inelastic deformation.
The book considers a wide range of structural types, including
separate chapters on frame buildings, wall buildings, dual
wall/frame building, masonry buildings, timber structures,
bridges, structures with isolation or added damping devices, and
wharves. These are preceded by introductory chapters discussing
conceptual problems with current force-based design, seismic
input for displacement-based design, fundamentals of direct displacement-based design, and analytical tools appropriate for displacement-based design. The final two chapters adapt the principles of displacement-based seismic design to assessment of exist
