This work collects revised and extended versions of 35 papers presented as plenary, semi-plenary, and keynote lectures at the Compdyn 2007 Conference. The first part of the book is devoted to computational structural dynamics, and the second part deals with computational earthquake engineering. Some specific topics investigated include structural dynamics design validation using the fuzzy finite element method, dynamic analysis of plates stiffened by parallel beams with deformable connections, simplified probabilistic seismic performance assessment of buildings, and structural health monitoring by Bayesian updating. To provide the reader with an overview of pertinent literature, all cited references, plus additional references on topics presented, are collected in a comprehensive list. The readership for the book includes researchers and students in civil, mechanical, naval, and aerospace engineering.

The increasing necessity to solve complex problems in Structural Dynamics and Earthquake Engineering requires the development of new ideas, innovative methods and numerical tools for providing accurate numerical solutions in affordable computing times.
This book presents the latest scientific developments in Computational Dynamics, Stochastic Dynamics, Structural Dynamics and Earthquake Engineering in thirty-five self-contained contributions. The selected state-of-the-art chapters are revised and extended versions of the papers which were presented as plenary, semi-plenary and keynote lectures at the thematic COMPDYN 2007 Conference.
This volume will benefit researchers and engineering professionals working on structural dynamics, earthquake engineering and computational mechanics. Readers will get acquainted with advanced computational methods and software tools, which can assist them in tackling complex problems in dynamic/seismic analysis and design. Moreover, it will raise the awareness of important application areas and the social impact of the scientific and technical fields involved.
