Abstract: An experimental study is presented in this paper on the behaviour of square R. C. columns of size 750 × 150 × 150 mm retrofitted with Glass fibre reinforced polymer (GFRP) sheets along with a brief review of literature. One column without GFRP and four columns complete wrapped with one, two, three and four layers of GFRP sheets have been tested for axial loading. The failure axial loads and failure modes of the columns have also been observed. A critical discussion is made with respect to increase in the strength of retrofitted columns with respect to the column without GFRP in order to explore the optimal use of GFRP for strengthening the R. C. columns. Further, an analytical model of RC column retrofitted with externally bonded FRP has also been proposed in compatibility with IS: 456-2000 [1] as the design guidelines on strengthening/retrofitting of concrete structures using externally bonded FRP laminates/sheets are yet to be recommended in India. The experimental ultimate load carr

Abstract: Rapid Prototyping (RP) has made massive strides in the technological industries and is at the fore front of innovation. However, the majority of them use different types of plastic and other materials including resins, flour etc., for the production of prototypes. They can only be used as visual prototypes in most instances and do not provide sufficient information for direct material testing which is needed to understand the mechanical properties for large scale production. The current methods employing powder metals have their limitations and are very expensive. There is an emphasis on the production of metal parts because they provide real time results rather than approximations and usually give more insight into the design parameters. This paper presents a novel rapid prototyping method for the production of cheap and high quality metal parts that are suitable for direct testing. The process is a combination of Laminated Object Manufacturing (LOM) and soldering technologies. The pr
