Carbon fiber strengthening and jacking of engineering structures
Abstract: This work is divided in two parts related to repair and strengthening of engineering structures: the first part deals with the design for strengthening of concrete structures by carbon fiber composites. The work focuses on a design program that had to be corrected before being released on the market according to the following steps: presentation of design rules and materials, development of an own program, comparison of the results of this program with a similar commercial program and last, verification of the commercial program to be released. The second part of this work deals with improvement of the design of reinforced concrete jacking consoles that are used at lifting bridge decks in order to carry out repair or replace bearing devices. In the first step, rules governing the fixing of consoles to bridge piers by pre-stressing bars were studied. Next, calculations have been carried out to reduce weight without detrimental effects on the load bearing capacity of the consoles. Finally, specifications and drawings need to manufacture the consoles have been produced.
