S Gall in northeastern Switzerland was strengthened in by bonding pultruded carbon-fiber polymer plates to the exterior surfaces of the concrete structures. Details on some of these and other early applications are described in Ref. Since then, there has been keen worldwide interest not only to use polymeric materials in strengthening structures, but also to examine their structural behavior under a variety of loading and environmental conditions.

Reference is a review highlighting some fundamental concepts pertaining to the use of FRP materials in structural rehabilitation; comprehensive expositions of past research activities, test results, and case studies on the same subject are given in a monograph Ref. To effectively design and execute a rehabilitation scheme.

Figure 3 Seismic Retrofitting There are four basic types of seismic retrofitting. In a large earthquake, the structure itself may become unsafe and need to be destroyed and rebuilt. For structures which are not very valuable, this type of seismic retrofitting is a reasonable option, if the company does not want to rebuild the structure altogether.

Some of these terms are a bit misleading, as no structure can be made entirely safe. It is important to preserve historic buildings with seismic retrofitting, but it is also important to ensure that the integrity of the building is not compromised.

This take extensive work and cooperation with companies which specialize in restoration of historic buildings. Miss K S.

There are primarily the following method used for this purpose. Whether a structure has been damaged due to overload, earthquake or materials deterioration, or whether the structure requires strengthening to resist increased future live loads, wind, or seismic forces, FRPs provide an efficient, cost- effective, and easy-to-construct means or reinforcing concrete members.

These advanced composites may be designed to act as flexural, shear, and confinement reinforcement. Use of these composites requires less disturbance to building occupancy, bridge traffic, and other functions than rehabilitation that uses additional steel reinforcement.
