-----------------------------------------------------------------------***------------------------------------------------------------------------------ABSTRACT: Steel concrete composite construction is a relatively a new concept for the construction industry. Steelconcrete composite elements are used widely in modern building construction. Steel-concrete composite systems for buildings are formed to act as a single unit by connecting the steel beam to the composite deck slab or profile deck sheet with the help of shear connectors. For medium to highrise buildings RCC structure is no extended economic because of their higher dead load, smaller amount stiffness, span limitation and hazardous formwork. In this present paper, G+9 multistorey building is modeled and analyzed using ETABS-2016. Three different types of model is madein this research. one for RCC, and remaining two for Steel Concrete Composite Structure with two different types of columns such as encased column and Concrete filled tubes. Cost Comparison for the above three types of buildings are done and comparison of parameters like Joint displacement, Story drifts and Story Shear is carried over and results are being compared.
steel-concrete system can provide very economical structural systems with great durability, rapid erection and superior seismic performance characteristics. The two materials are mostly used as building material those are steel and concrete for structures ranging from sky scrapers to pavements, although these materials possess different characteristics and properties, they both like to complement each other in various ways. Composite members are made up of two different materials such as steel and concrete which are used for beams and columns. The steel and concrete structures have extensive uses in multistory commercial buildings and factories as well as in case of bridges. Steel and concrete have almost the same thermal expansion, concrete is capable in taking compression loads and steel is exposed to tensile loads. Composite structures are becoming popular and preferred choice of structural Engineers. In composite construction preliminary construction loads will be supported by steel frame members including the self weight during construction and then concrete is cast around the section or concrete is poured inside the tubular section.
KEYWORDS: Profile deck sheet, Encased Column, Joint displacement, Story drifts, Story Shear.
1.INTRODUCTION
2. ELEMENTS OF COMPOSITE STRUCTURE
In the previous years, for the design of a building, the choice was usually between a concrete structure and a masonry structure. But the failure of many multi-storied and low-rise R.C.C. and masonry buildings due to earthquake has enforced the structural engineers to look for the alternate method of construction. Use of composite or hybrid material is of particular interest, due to its significant prospective in improving the overall performance through rather modest alterations in manufacturing and constructional technologies. In India, most of the consulting engineers are unwilling to accept the use of composite steel-concrete structure because of its unfamiliarity and complexity in its analysis and design. But literature says that if properly configured, then composite
2.1 Shear Connectors Shear connections are crucial for steel concrete construction as they integrate the compression capacity of supported concrete slab with supporting steel beams to improve the load carrying capacity as well as overall rigidity.
