by Julius S6lnes An Advanced Study Institute on engineering seismology and earthquake engineering was held in Izrrir, 'rurkey July 2-13, 1973 under the auspices of the Scientific Affairs Division of NATO. The Institute was organized by an organizing committee headed by the two scientific directors and with representation by the Turkish National Science Foundation, Turkish National Committee for Earthquake Engineering, the Middle East Technical University and the Aegean University. 93 scientists and engineers of 18 countries took part in the work of the Institute which comprised 10 working days with lectures, discussions and panel meetings. The main lecture topics of the Institute were covered in five main sections: 1. Generic causes of earthquakes. 2. Ground motion and foundation response. 3. Earthquake response of structures and design consi derations. 4. Codes and regulations; implementation. 5. Earthquake hazards and emergency planning. Upon completion of each section, general discussion and short presentations by several of the participants took place and summary statements were offered by the main lecturers. The atmosphere of the meetings was in- VI formal and cordial thus giving rise to many unorthodox and newly conceived ideas."

Stochastic Processes and Random Vibrations Theory and Practice JAlA-us SA3lnes University of Iceland, ReykjavA-k, Iceland This book covers the fundamental theory of stochastic processes for analysing mechanical and structural systems subject to random excitation, and also for treating random signals of a general nature with special emphasis on earthquakes and turbulent winds. Starting with basic probability calculus and the fundamental theory of stochastic processes, the author progresses onto engineering applications: systems analysis and treatment of random signals. The random excitation and response of simple mechanical systems and complex structural systems is discussed in some detail. Extreme conditions such as distribution of large vibration peaks, random excursions above certain limits and mechanical failure due to fatigue are then addressed. The text also offers a discussion of some well-known stochastic models and an introduction to signal processing and digital filters. Numerous worked examples are included: distribution of extreme wind speeds, analysis of structural reliability, earthquake response of a tall multi-storey structure, wind loading of tall towers, generation of random earthquake signals and earthquake risk analysis.
