Foreword
ItisagreatpleasuretopresentIntroductiontoDynamicsofStructuresandEarth-
quake Engineering by Gian Paolo Cimellaro and Sebastiano Marasco. The book
locates itself between elementary books and books for advanced graduate studies.
Thebookisdivided intothreeparts:“PartI–Dynamics ofStructures”introduces
themainconceptsofdynamicsofstructures.“PartII–IntroductiontoEarthquake
Engineering”introducesthebasicconceptsofseismology,seismichazardanalysis,
anddifferentanalysismethods.“PartIII–SeismicDesignofBuildings”describes
howtomodelstructuresinseismiczonesandthebasicconceptsofcapacitydesign
as well as new innovative techniques for the design of new and retrofit of existing
buildings. The typical coverage of “Dynamics of Structures” starts properly with
anintroductionofthefundamentalconceptsofstructuraldynamics,withemphasis

inaneasyandaccessiblewaythelatestupdatesinthefield.Nopreviousknowledge
of structural dynamics is assumed, making this book suitable for the reader that
is learning the subject for the first time. However, the following background is
required:
(cid:129) Static analysis of structures including statisticallyindeterminate structures and
matrixformulation
(cid:129) Rigidbodydynamics
(cid:129) Mathematics:linearalgebraandordinaryandpartialdifferentialequation
With respect to other classical books on dynamics of structures, this book
emphasizes the application of energy methods and the analysis in the frequency

PartIintroducesthemainconceptsofdynamicsofstructures.PartIIintroduces
the basic concepts of seismology, the seismic hazard analysis, and the different
analysis methods. Part III describes how to model structures in a seismic zone
andthebasicconceptsofcapacitydesign(Chap.15)aswellasthenewinnovative
techniques for the retrofit of new and existing buildings, such as passive energy
dissipatingsystems(Chap.17),tunedmassdampers(Chap.18),andbaseisolation
(Chap.19). Chapter 20 focuses on the seismic behavior of masonry structures,

probability.
Several figures have been carefully designed and executed to be pedagogically
effective. Many of them involve the use of computer simulations. Most of the
references have been omitted in the book to avoid distracting the reader; however,
a selected list of publications has been added at the end of each book chapter for
furtherreading.

Acknowledgments
This book has been written during a year of sabbatical leave that I spent at the
University of California, Berkeley. It is the result of the research experience with
mystudentsandoftheyearsthatIhavetaughtinthecourseofseismicengineering
at the Politecnico di Torino. I am grateful to several present and former students
whohelpedintherevisionofthebooksuchasmycurrentPh.D.student,Sebastiano
Marasco, who is the coauthor of this book and is one of the developers of the

from MIT who was a visiting scholar at the Politecnico di Torino, helped with
the revision of the English language of the script. Students Alessandro Cardoni,
