Earthquake
Engineering
Definition
Earthquake
Engineering can be defined as the branch of engineering devoted to mitigating
earthquake hazards. 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:
a. To prevent non-structural damage in frequent
minor ground shaking
b. To prevent structural damage and minimize
non-structural damage in occasional moderate ground shaking
c. 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.
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.
