International Journal for Research in Applied Science & Engineering Technology (IJRASET), 2022

Composite Structure is quickly gaining acceptance in India's non-residential multi-story building sector. The reason for considering composite construction is simple: Steel is best in tension and concrete is best in compression. Combining these two materials strengthens their structural properties, which can be used to create a highly effective and lightweight design. Steelconcrete composite building systems are formed by connecting the steel beams to the profiled deck slab using shear connectors so that they function as a single unit, and for columns steel section is encased in concrete. In this present work, comparative study of G+15 R.

In India reinforced concrete structures are mostly used since this is the most convenient & economic system for low-rise buildings. However, for medium to high-rise buildings this type of structure is no longer economic because of increased dead load, less stiffness, span restriction and hazardous formwork. So the structural engineers are facing the challenge of striving for the most efficient and economical design solution. Use of composite material is of particular interest, due to its significant potential in improving the overall performance through rather modest changes in manufacturing and constructional technologies. Steel-concrete composite columns are used extensively in modern buildings. Extensive researches on composite columns in which structural steel section are encased in concrete have been carried out. In-filled composite columns, however have received limited attention compared to encased columns. In this study E-Tabs nonlinear software is used for simulation of steel concrete composite (CFT) with steel reinforced concrete structures (RCC) of G+14, G+19 and G+24 stories each are considered for comparative study. Comparison of parameters like time period, storey displacement and storey drift is done.

Steel concrete composite construction has gained wide acceptance world wide as an alternative to pure steel and pure concrete construction. The use of steel in construction industry is very low in India compared to many developing countries. There is a great potential for increasing the volume of steel in construction, especially in the current development needs India and not using steel as an alternative construction material and not using it where it is economical is a heavy loss for the country. In this paper study of Four various multistoried commercial buildings i.e. G+12, G+16, G+20, G+24 are analysed by using STAAD-Pro software. Where design and cost estimation is carried out using MS-Excel programming and from obtained result comparison can be made between R.C.C and composite structure.

Steel-concrete composite construction means steel section encased in concrete for columns & the concrete slab or profiled deck slab is connected to the steel beam with the help of mechanical shear connectors so that they act as a single unit..Steel-concrete composite with R.C.C. options are considered for comparative study of G+5 storey office building with 3.658 m height, which is situated in earthquake zone III(indore)& wind speed 50 m/s. The overall plan dimension of the building is 56.3 m x 31.94 m.Equivalent Static Method of Analysis is used. For modeling of Composite & R.C.C. structures, staad-pro software is used and the results are compared; and it is found that composite structure more economical.

Steel concrete composite construction has gained wide acceptance world wide as an alternative to pure steel and pure concrete construction. The use of steel in construction industry is very low in India compared to many developing countries. There is a great potential for increasing the volume of steel in construction, especially in the current development needs India and not using steel as an alternative construction material and not using it where it is economical is a heavy loss for the country. In the present work steel concrete composite with RCC options are considered for comparative study of G+15 story building which is situated in earthquake zone-IV and for earthquake loading, the provisions of IS: 1893 (Part1)-2002 is considered. A three dimensional modelling and analysis of the structure are carried out with the help of ETAB software.

Steel-concrete composite construction has gained wide acceptance world wide as an alternative to pure steel and pure concrete construction. However, this approach is a relatively new concept for the construction industry. Steel-concrete composite elements are used extensively in modern buildings. Extensive research on composite column, composite beam and deck slab in which structural steel section are encased in concrete have been carried out. However, for medium to high-rise buildings R.C.C structure is no longer economic because of increased dead load, less stiffness, span restriction and hazardous formwork. The results of this work show that the Composite structures are the best solution for high rise structure as compared to R.C.C structure.

The project entails the analysis, planning, and design of a steel-concrete composite building. The planned building is a G+4 structure with floors that are each 3.75 metres high. The building's total plan is 39.6 m by 12.3 m. The structural planning, load calculations, analysis by 2D modelling using STAAD-Pro V8i, design of composite floors and columns, design of steel beams, design of RCC beam, design of RCC column, and design of RCC slab are all included in the analysis and design process. According to the Indian Standard Code of Practice, analysis has been performed for a variety of load combinations. In this project, a comparable RCC structure is also created so that the costs of both the steel composite and the RCC structure has been compared.

Composite structure is gaining more popularity now days in construction area. Composite column like concrete filled steel tube is component with good performance resulting from the confinement effect of steel with concrete and design versatility. Composite structure has more advantage over RCC and steel frame structure. The study about the behavior and the characteristics of composite over RCC and steel is the prime need. In India concrete is very popular material of construction especially in case of medium and low risebuildings. And in case of high rise buildings steel is generally used and the composite construction is not that much popular but it is possible that composite construction can be more beneficial in case of medium and high rise buildings. Steel concrete composite construction can be built in place of RCC structures to get maximum advantage of steel and concrete and to produce efficient and economic structures. It is the decision of contractor or owner that which type...

It is a customary in our country to use RCC is used to construct the buildings up to G+3 height building. The low-income groups prefer RCC. But for the high rise and mid height structures the RCC type is not economical as the dead load increases and longer spans are not favourable. The economic and less time consuming design solutions are required. The composite structures can replace RCC structures. The concrete and steel are used in composite structures. The composite structure designs are complex and less efficient that is why not so popular. The developed countries have wider acceptance for the composite structures as compared with pure steel and concrete frames. All the plus points of steel and concrete are incorporated in composite type frame work. The structures take lesser time in construction and much waste is produced on the construction sites. This paper covers the review on the composite construction prevalent globally.
