Earthquake Resistant Buildings
This book provides a general introduction to the topic of three-dimensional
analysis and design of buildings for resistance to the effects of earthquakes. It is
intended for a general readership, especially persons with an interest in the
design and construction of buildings under servere loadings.
A major part of design for earthquake resistance involves the building
structure, which has a primary role in preventing serious damage or structural
collapse. Much of the material in this book examines building structures and,
specifically, their resistance to vertical and lateral forces or in combinations.
However, due to recent discovery of the vertical component of acceleration of
greater magnitude in the kobes’ earthquake the original concept of ‘‘lateral
force only’’ has changed. This book does advocate the contribution of this
disastrous component in the global analytical investigation.
When the earthquake strikes, it shakes the whole building and its contents.
Full analysis for design layout and type of earthquakes, therefore, must include
considerations for the complete building construction, the building contents
and the building occupants.
The work of designing for earthquake effects is formed by a steady stream of
studies, research, new technologies and the cumulative knowledge gained from
forensic studies of earthquake-damaged buildings. Design and construction
practices, regulating codes and professional standards continuously upgraded
due to the flow of this cumulative knowledge. Hence, any book on this subject
must regularly be updated. Since the effects are not the same, the earthquake
forces are always problematic.
Over the years, earthquake has been the cause of great disasters in the form
of destruction of property and injury and loss of life to the population. The
unpredictability and sudden occurrence of earthquakes make them somewhat
mysterious, both to the general public and to professional building designers.
Until quite recently, design for earthquakes – if consciously considered at all –
was done with simplistic methods and a small database. Extensive study and
research and a great international effort and cooperation have vastly improved
design theories and procedures. Accordingly, most buildings in earthquakeprone
areas today are designed in considerable detail for seismic resistance.
