Structural aspects of repair
3.1 Structural repair of concrete
Reinforced and prestressed concrete are structural materials. Two major
failures (Wood, undated, accessed July 2010; Wood, 2003, 2008)
following inadequate repair contracts have highlighted the importance of
structural consideration of both deterioration and repair. When damage or
deterioration has occurred necessitating a repair, the changes to the structure
before, during and after the repair need to be a primary consideration. This
will throw up a range of questions about the structure and how the actual
build quality relates to the designers' intentions, current standards and how
deterioration has altered this.
The IStructE publication 'Appraisal of existing structures' (IStructE,
2010) deals comprehensively with the process of structural appraisal. If
repaired half joint and lower part of the cantilever can be seen hanging down.
