ABSTRACT

Most of the commercial and residential buildings in the country are RCC, which is a versatile material for construction possess up good properties in compression as concrete and in tension as steel. Also, we know that coefficient of thermal expansion of concrete and steel are nearly same. But there is one of the most common reason of failure of RCC building is due to corrosion of steel. This will happen after providing sufficient clear cover to reinforcement as per codal provision. So, to overcome that problem we may replace the main reinforcement as steel to as basalt rebars, which has same coefficient of thermal expansion as concrete and also will not get corroded when exposed to external conditions.

The present study will discuss the influence of basalt rebars instead of HYSD bars in RCC building of different height and there will be comparison of material quantity required of steel and basalt rebars. Codal provision used for design of structure elements like beam, column, slabs and footing will be IS 456 in that case of designing mechanical property will be replace by basalt rebar properties. The study involves analysing the building for different heights considering load as per codal provision using on STAAD V8i sticking to the IS 456:2000 guidelines. The study brings out that how basalt rebars is the one of the options to use in place of steel as a reinforcement in RCC buildings.
