      In 1997, William G. Godden, Emeritus Professor of Civil Engineering, donated his nine-volume slide set, Structural Engineering Slide Library, to the Earthquake Engineering Research Center Library at the University of California at Berkeley.  This site is based on the original text for Set J: Earthquake Engineering, by V. V. Bertero, an illustrated introduction to earthquake engineering principles. 
      The web version was designed and created by Vivian Isaradharm, a student at UC Berkeley.
      The site may be navigated sequentially, through the Table of Contents or from the List of Slides.  Reproductions of these slides are available from the EERC Library.

            In developing the Structural Engineering Slide Library as a resource for teaching structural and architectural engineering, the topic of structural dynamics is of prime importance. Earthquake engineering is one of the most visible aspects of this field and one of the most easily illustrated due to the extent and variety of structural damage in earthquakes; thus it was decided to devote a volume to this subject.
            Professor Bertero, of the Department of Civil Engineering and Earthquake Engineering Research Center, University of California, Berkeley is uniquely qualified for this undertaking.  This publication is the outcome of extensive teaching in structural dynamics, theoretical and experimental research on structural components and structural systems in the field of earthquake-resistant design, as well as on-site studies of structural damage in major earthquakes in Alaska, Argentina, Algeria, California, Guatemala, Japan, Nicaragua and Venezuela.
            The following material, usually seen only at conferences, is now made available for general use, and will be particularly useful as an aid to the teaching of structural dynamics and earthquake engineering.

Definition

      Earthquake Engineering can be defined as the branch of engineering devoted to mitigating earthquake hazards [1].  In this broad sense, earthquake engineering covers the investigation and solution of the problems created by damaging earthquakes, and consequently the work involved in the practical application of these solutions, i.e. in planning, designing, constructing and managing earthquake-resistant structures and facilities.

Objectives and Scope of this Volume

      The main objective of this volume is to illustrate to students of structural and architectural engineering the problems and solutions in attaining efficient earthquake-resistant structures and facilities. 
      To achieve this objective, after a brief discussion of the general goals in seismic-resistant design and construction of structures and facilities, the different sources of damage that can be triggered by an earthquake are discussed and illustrated.  Emphasis is placed on the discussion and illustration of damage induced by vibration on timber, masonry, concrete and steel structures.
      The importance of a comprehensive approach to the problem of earthquake resistant construction is emphasized next and the need for placing more emphasis on conceptual design is discussed by offering guidelines for and illustrations of efficient seismic-resistant design.
      The need for research in earthquake-resistant design and construction is briefly discussed and examples of integrated experimental and analytical investigations in the development of modern seismic-resistant design are also shown.

General Goals in Seismic-Resistant Design and Construction

      The philosophy of earthquake design for structures other than essential facilities has been well established and proposed as follows:

  1. To prevent non-structural damage in frequent minor ground shaking
     
  2. To prevent structural damage and minimize non-structural damage in occasional moderate ground shaking
     
  3. To avoid collapse or serious damage in rare major ground shaking

      This philosophy is in complete accord with the concept of comprehensive design.  However, current design methodologies fall short of realizing the objectives of this general philosophy [2].

      The implementation of this philosophy presents serious problems particularly in quantifying the different types of damage (structural and non-structural) and what constitutes frequent minor, occasional moderate, and rare major earthquake ground shaking.
