STRENGTHENING CHOICES FOR THE REPAIR & RETROFIT OF CONCRETE BRIDGE STRUCTURES WITH FRP

Article Summary   by:toffi_75     Original Authors: J. M. Eyre; T. J. Ibell; A. Nanni
ª
 
At
present there exist numerous, approved documents and guidelines across Europe,
the US, Japan and Canada, giving detailed information on the various
applications available that provide for the strengthening of concrete
structures with Fibre Reinforced Polymers (FRP). Such guidelines offer a detailed
overview of the principles involved in the design of strengthening for
deficient beams, columns and slabs, but do not offer codified approaches for
individual materials and techniques, or the necessary specialist bridge related
criteria. The information and understanding gained from this study is intended
for use in directing the generic approach to future FRP design strategies,
through the unification of material, system & installation procedure
selection and inspection & monitoring regimes.


Software
has been developed by the authors to provide a rule-based, logic-programmed
.FRP Strengthening System. Selection Toolkit defining the extent of required
superstructure strengthening following diagnosis and recommendation for
pre-installation treatment of the defects and degradation established from
analysis of assessment and inspection results. The design process protocol
incorporated in the software, consciously targets the concerns of largely
inexperienced engineers in this field, particularly those of graduate level
training, whilst also attempting to meet the knowledge demands of the Project
Engineer or Department of Transportation Investigating Official, responsible
for compilation of a preliminary strengthening scheme proposal, for later
submission to tender.
