Preface
In conventional seismic design the concept of fixed base is deeply embedded in practice. This
design approach is employed largely by virtue of its simplicity and this simplicity enables
structural engineers to proceed with their design in isolation of geotechnical consideration.
In this simple design approach the earthquake loading is assumed to be independent of the
system being loaded. This decoupling of the system and earthquake loading does not reflect
the reality and can have severe consequence in both magnitude and frequency content of the
system response. In the current approach the earthquake load is assumed as either the ground
motion recorded at ground surface free of any influence of adjacent structures or is simu-
lated based on a target design spectrum. An aspect of the complexity of the system is, as far
as structures are concerned, that they are a closed system, while in the case of the supporting
soil the system is without boundary. Consequently, the soil-foundation-structure systems are
not unique with respect to their properties because of the strain-dependent nature of their
characteristics.
In reality, structures are not isolated, especially in intensely populated regions. Adjacent
structures influence each other while responding to earthquakes. This influence results from
the interaction between each structure with the supporting soil, between adjacent structures
through common supporting ground and the alteration of incoming seismic waves from the
summation of the interaction of all clustered structures. In addition, the compounding effect
of high strain cyclic response of cohesionless soil will induce highly nonlinear behaviour
leading to a strong local site effect. This strong nonlinear site response can have severe con-
sequence for structures. This aspect cannot be considered in the design of structures when a
fixed base is assumed.
This workshop is one of the activities of the research project under the auspices of the
Natural Hazards Research Platform entitled “Impact of liquefiable soil on the behaviour of
coupled soil-foundation-structure systems in strong earthquakes” funded by the Ministry
of Business, Innovation and Employment. The papers and presentations were by invitation
only. However, the workshop itself was open to interested members of the public. The speak-
ers were experts in their field and originated from Japan, Australia, USA, China, New Zea-
land, Germany and Chile.
The proceedings consisted of 19 papers, which were revised by the authors after the work-
shop. The editors consider that a revision of the papers will lead to enhanced understanding
of the seismic performance of multiple coupled systems. This understanding when incorpo-
rated in everyday engineering design has the potential to facilitate a safer seismic environ-
ment at a lower cost, especially in large cities of the world.
