Abstract

Steel-Concrete composite construction are assembly of steel beam, concrete floors and profile sheets by achieving the shear connection with the help of mechanical shear keys. Composite structure is very famous now days as they provides structural efficiency with rapid and also provides affordable wide range of structures. In this study, composite structure and reinforced concrete structures are considered for study of G+4 residential building. This building comes in earthquake zone II. Equivalent Static Method of analysis is used. For modelling of Composite and reinforced concrete structures, Results were analysed in STAAD.pro software and compared for displacement, S.F. and B.M. The displacement in top storey, bottom storey and 3rd storey is more in reinforced concrete as compared to composite structure. The bending moment in top storey, bottom storey and 3rd storey is more in reinforced concrete as compared to composite structure. Similarly shear forces and axial forces were compared for reinforced concrete building and composite building.

Introduction

India is a developing country as enormous house building development is occurring in different parts of the country. Since 30% of Indian populace lives in towns and urban communities consequently development is more in urban spots. The prerequisite of shelter is gigantic yet there will consistently be a lack of house accessibility as the present development innovation can’t satisfy the rising need each year. Subsequently one needs to think for elective development framework like pre-built steel structures. Subsequently one needs to think for elective development framework like pre-built steel structures.[2] India has an introduced steel limit of 35 to 40 million tones and clear steel utilization is around 27 to 30 million tonnes. There is a surplus limit of level steel items accessible in India especially of hot and cold moved sheets. These steel parts can be used in the development of pre-built structure segments. In India, fortified solid individuals are generally utilized in the confining framework for the vast majority of the structures since this is the most advantageous and financial framework for low-ascent structures. These steel parts can be used in the development of pre-built structure segments. In the pre-built structure idea, the total planning is done at the processing plant and the structure parts are brought to the site in knockdown condition. These parts are then fixed/jointed at the site and rose with the assistance of cranes. The pre-built structure calls for extremely quick development of structures and with great stylish looks and quality development. Pre-built Buildings can be utilized widely for development of modern and private structures. The structures can be multi-celebrated (4-6 stories). These structures are reasonable for different natural perils. This study was carried out to give a concise depiction of various components of steel concrete framework for structures, to examine the cost-adequacy and duration of G+ 4 residential building projects of composite frames over conventional reinforced concrete frames for buildings. Analysis was carried out by using STAAD.pro and deflection, axial forces, maximum bending moment of different components of the building was carried out

Conclusion

From the above research it can be said that the deflection in top storey, bottom storey and 3rd storey is more in reinforced concrete structure as compared to composite structure. The bending moment in top storey, bottom storey and 3rd storey is more in reinforced concrete structure as compared to composite structure. It can also be concluded that 1. The axial forces in composite frame structure are 20% more as compared to reinforced concrete columns. 2. Composite beam though possess heavy self-weight but its moment carrying capacity is 3 times more than the reinforced concrete structure. 3. Percentage of steel is within the permissible limit of concrete, it indicates practically no shear as compared to reinforced concrete structure. 4. The storey drift in conventional structure less than that of composite framed structure but the deflection is within the permissible limit. 5. No time pollution saves 61.11% of time. 6. Foundation cost will be reduced due to the light weight construction as compared to reinforced concrete structure. 7. Composite frame structures are suggested for high rise structures.
