This book provides a new solid background for the design of reinforced
concrete structures. The practice of using f'c as a design parameter has
been successful in the past and will continue to do so since there are
numbers of strength reduction and load enhancement factors incorporated
in the current design codes, which are entirely based on compressive
strength of concrete. As a consequence the current design practice is
not only leading to a more expensive design solution but also on the
other hand suggests periodic revision of the building codes, as the
upper limit of the concrete's compressive strength has never been a
constant. Having said that, the optimistic solution for the problem is
the incorporation of fracture mechanics in the current design codes in
general and more specifically concrete structures can also be designed
based on the characteristic length of the concrete mix.
