Managing Retrofit Project.

Abstract

Many existing reinforced concrete structure in

present world are inadequate for earthquakes. Recent

earthquakes which occurred during last decades have

indicates that major damage occurred was not directly due

to the poor performance of structure during earthquakes.it

is recognized that the most effective method of reducing

risk of damaging structure is sesmic retrofitting. In recent

year significant improvement of retrofitting techniques.

Thus study highlights the principals of assessing and

retrofitting of structure against seismic events.. Finite

Element Method used to investigate the performance of the

building during the earthquake and to check the behavior

of the structure after applying retrofitting techniques. The

methods such as steel and concrete jacketing and

application of fiber reinforced polymer (FRP) composites,

which are used to improve the load bearing capacity of

individual structural elements, are highlighted and

methods such as shear walls & shear cores, which can be

used to improve overall stability, are enlisted and the

factors that governs the decision for retrofitting of the

structures are discussed.
