A comprehensive investigation of the Multiple Support Response Spectrum (MSRS) method for seismic analysis of bridges and other multiply supported structures is presented. The method accurately accounts for the spatial variability of ground motions, including the effects of incoherence, wave passage, and spatially varying site response. The structural response is obtained in terms of response spectra and peak displacements at individual support degrees of freedom, and a coherency function that characterizes the three spatial variability effects. Special attention is given to the effect of site response arising from variation in the soil conditions at different supports of the structure. Through extensive comparisons with time history analysis, the validity of the MSRS rule and the site response component of the coherency function are established. Methods for estimating the site frequency response function, needed in the coherency model, are developed and examined. These models and rules are implemented in the MSRS code for application to three-dimensional, multiply supported structures. Using the MSRS code, extensive parametric studies are performed for two example bridge structures. The report concludes with a summary of guidelines for practical implementation of the MSRS rule.

The proceedings contain contributions presented by authors from more than 30 countries at EURODYN 2002. The proceedings show recent scientific developments as well as practical applications, they cover the fields of theory of vibrations, nonlinear vibrations, stochastic dynamics, vibrations of structured elements, wave propagation and structure-borne sound, including questions of fatigue and damping. Emphasis is laid on vibrations of bridges, buildings, railway structures as well as on the fields of wind and earthquake engineering, repectively. Enriched by a number of keynote lectures and organized sessions the two volumes of the proceedings present an overview of the state of the art of the whole field of structural dynamics and the tendencies ot its further development.

Given the risk of earthquakes in many countries, knowing how structural dynamics can be applied to earthquake engineering of structures, both in theory and practice, is a vital aspect of improving the safety of buildings and structures. It can also reduce the number of deaths and injuries and the amount of property damage.The book begins by discussing free vibration of single-degree-of-freedom (SDOF) systems, both damped and undamped, and forced vibration (harmonic force) of SDOF systems. Response to periodic dynamic loadings and impulse loads are also discussed, as are two degrees of freedom linear system response methods and free vibration of multiple degrees of freedom. Further chapters cover time history response by natural mode superposition, numerical solution methods for natural frequencies and mode shapes and differential quadrature, transformation and Finite Element methods for vibration problems. Other topics such as earthquake ground motion, response spectra and earthquake analysis of linear systems are discussed.Structural dynamics of earthquake engineering: theory and application using Mathematica and Matlab provides civil and structural engineers and students with an understanding of the dynamic response of structures to earthquakes and the common analysis techniques employed to evaluate these responses. Worked examples in Mathematica and Matlab are given. - Explains the dynamic response of structures to earthquakes including periodic dynamic loadings and impulse loads - Examines common analysis techniques such as natural mode superposition, the finite element method and numerical solutions - Investigates this important topic in terms of both theory and practise with the inclusion of practical exercise and diagrams
