1. INTRODUCTION
Conventional vibrated stone columns are typically used to improve the engineering properties of soft soils for the support of lightly and moderately loaded structures such as motorway embankments and large diameter storage tanks. The technique generally comprises replacing soft soil with columns of crushed rock gravel that act to stiffen the soil mass, increasing stability and reducing the time rate of consolidation. Although generally considered to be suited to soils with undrained shear strengths (su) abo ....etc

With the advancements in the engineering structure (high rise building and heavily loaded structures) the concrete filled steel tubular members are found to be most efficient. This is seen from a voluminous research and structural evidences around some parts of the world.From 1960s the engineers of advanced countries are studying CFST members for its effective use in the engineering structures. Many experiments have been performed under CFST columns but code have been arrived for its effective use. Even though from sixties, there are a few use ....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

Deep beams are structural members loaded as simple beams in which a significant amount of the load is carried to the supports by a compressive force that combines the charge and the reaction. As a result, the strain distribution is no longer considered linear, and the shear deformations become significant in comparison with pure bending.

Horizontal load-bearing floor slabs, short-section beams carrying heavy loads and transfer beams are examples of deep beams. The deep beam is a beam having a large depth / thickness ratio and a depth ratio o ....etc

Construction material subjected to repetitive or cyclic loading have to be qualified for their fatigue behaviour. Generally their behaviour is considered satisfactory if they withstand two million cycle of repetitive loading without distress or failure at that required mean stress level and range stress.
The recent research in reinforcing Portland cement based material with randomly distributed fibres was spurred by pioneering research or fibre reinforced concrete (FRC) conducted in the United state in the 1960s.The addition of fibre in the co ....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
