1.1. SAFETY OF CIVIL STRUCTURES Society expects that the failure of
civil structures is extremely rare and relies on the care and
expertise of the professionals involved in the design, construction
and maintenance of structures. This is in particular true for
public technical systems such as transportation or energy supply
systems and structures such as bridges. Structural safety may be
defined as follows: "Adequate safety with respect to a hazard is
ensured provided that the hazard is kept under control by
appropriate measures or the risk is limited to an acceptable value.
Absolute safety is not achievable." It is thus not the structure as
such that is designated safe but rather the people, goods and the
environment in its surroundings. The continued use of existing
structures is of great importance because the built environment is
a huge economic and political asset, growing larger every year.
Nowadays evaluation of the safety of existing structures is a major
engineering task, and structural engineers are increasingly called
upon to devise ways for extending the life of structures whilst
observing tight cost constraints. Also, existing structures are
expected to resist against accidental actions although they were
not designed for. Engineers may apply specific methods for
evaluation in order to preserve structures and to reduce a client's
expenditure. The ultimate goal is to limit construction
intervention to a minimum, a goal that is clearly in agreement with
the principles of sustainable development.
