Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of modern seismic codes in the late 1960s for developed countries (US, Japan etc.) and late 1970s for many other parts of the world (Turkey, China etc.), many structures we ....etc

INTRODUCTION
In the last 200 years, rapid advances in construction materials technology have enabled civil engineers to achieve impressive gains in the safety, economy, and functionality of structures built to serve the common needs of society. Through such gains, the health and standard of living of individuals are improved. The use of FIBRE REINFORCED POLYMERS (FRP) as reinforcement for structures is rapidly gaining appeal. Fiber reinforced polymer (FRP) systems are high-strength, lightweight reinforcement ....etc

ABSTRACT
This paper presents the results of experimental studies concerning the flexural strengthening of RC beams using externally bonded Slurry Infiltrated Mat CONcrete (SIMCON) laminates. A total of four reinforced concrete beams were cast and tested in the laboratory over an effective span of 3000 mm. Three beams were strengthened with bonded SIMCON laminate at the bottom under virgin condition and tested until failure; the remaining one beam was used as control specimen. Static responses of all the beams we ....etc

Reinforced concrete structures often have to face modification and improvement of their performance during their service life. The main contributing factors are change in their use of ,new design standards, deterioration due to corrosion in the steel caused by exposure to an aggressive environment and accident events such as earthquakes .In such circumstances there are two possible solutions: replacement or retrofitting.
Retrofitting of flexural concrete elements are traditionally ac ....etc

REPAIRS, REHABILITATION AND RETRO-FITTING
Significance of Ferrocement repairs
After, we in India, started manufacture of concrete in years 1930 s, the negative aspect of concrete started showing after sometime as below:-
- Deterioration due to poor workmanship, particularly high water content and corrosion of reinforcement and R.C.C. Technology being new.
- Leakages in concrete due to rain water as well as in water retaining structures
This menace become conspicuous after construction works which became old about 20 to 30 years. We star ....etc
