This study examines the composite structure that is increasing commonly in developing countries. For medium-rise to high-rise building construction, RCC structures is no longer economical due to heavy dead weight, limited span, low natural frequency and hazardous formwork. The majority of commercial buildings are designed and constructed with reinforced concrete, which largely depends on the existence of the constituent materials as well as the quality of the necessary construction skills, and including the usefulness of design standards. Conventional RCC structure is not preferred nowadays for high rise structure. However, composite construction, is a recent development in the construction industry. Concrete-steel composite structures are now very popular due to some outstanding advantages over conventional concrete and steel structures. In the present work, RCC and steel-concrete composite structure are being considered for a Dynamic analysis of a G+25-storey commercial building of uniform and optimized section, located at in seismic zone IV. Response Spectrum analysis method is used to analyze RCC and composite structure, CSI ETABS v19 software is used and various results are compared such as time period, maximum storey displacement, maximum storey stiffness. Maximum storey shear and maximum stoey overturning moment.
In India, most building structures fall into the low-rise building category. Therefore, reinforced concrete structure are increasingly used in these constructions because of their very convenient and economical construction. However, urban populations are growing exponentially and land is limited, requiring buildings to grow vertically in these cities. To this end, many mid-to-high-rise buildings are currently being built. For these skyscrapers, using composite components for construction has been found to be more effective and economical than using reinforced concrete components. The popularity of composite structure in cities is due to their advantages over traditional reinforced concrete structures. Reinforced concrete frames are used in low rise buildings due to their light load. However, traditional reinforced concrete structures cannot be used in medium and high-rise buildings due to their increased weight, limited span, low stiffness and vulnerable to hazards framing system. Steel is rarely used in the Indian construction industry compared to other developing countries such as China and UK. With the development in India, there is an urgent need to do more research in the field of construction and develop new and improved technology of steel composite as a building material in an economical construction. Reinforced concrete composite frames use more steel and have proven to be an economical approach to solving mid-to-high building structural problems.
A. Why Composite
In this thesis two RCC model, one is uniform section type another is optimized section type and two composite model, one is uniform section type another is optimized section type are taken. Dynamic analysis (Response Spectrum method) is done using CSI ETBAS v19 software.
The objectives of this paper are: -
II. COMPOSITE STRUCTURE
A composite member is defined as consisting of a rolled or a built-up structural steel member covered with reinforced concrete or a structure bound to reinforced concrete. The composite structural elements are constructed so that the shapes of the steel structure and concrete act together to resist axial compression, flexure and torsion.
Component of composite structure: -
???????A. Advantages Of Composite Structure
III. MODELLING AND ANALYSIS
This chapter explained that the 3D building model is analyzed using the Response Spectrum method. The commercial building models G+25 RCC and Composite are analyzed using ETABS 19 software. The seismic codes are unique to a particular region of the country. In India, Indian Standard for Design of Seismic Structures IS 1893:2016 is the main standard that provides the outline for the calculation of seismic design forces.
The process of finding the best economic structural outcomes with maximum benefit at minimum material or cost is called optimization. Due to recent advances in structural design, it is very easy to obtain a safe design, but difficult to find an economical design, so optimization techniques are needed to obtain most economically efficient design.
This is beneficial in many ways such as saving materials, reducing concrete usage. Therefore, optimization has gained momentum in structural engineering. In this project, optimization of columns and beam is carried out.
B. Step Of Section Optimization
The Dynamic Analysis is conducted on two different model using CSI ETABS19, several values ??of model were found out from RCC and Composite Structure. IS 1893-2016 guidelines is used for the Dynamic Analysis of four model of G+25 storey. these structures are analyzed for RCC and Composite Structure of uniform and optimized section.
Therefore, total four models are used for analyzing the response of the building. The result of frequency, time period, displacement, drift, storey shear, storey overturning moment and storey stiffness are compared for both RCC and Composite structure of uniform and optimized section.
A. Time Period 1) After optimization of RCC structure, time period increased by 22.4% as compare to uniform RCC section. 2) In a similar manner, time period increased by 28.6% for optimized section of composite structure as compare to uniform composite section. B. Storey Displacement 1) Maximum storey displacement increased by 28.2%.for optimized RCC section with respect to uniform RCC section. 2) In a similar manner, maximum storey displacement increased by 40.7% for optimized section of composite structure as compare to uniform section. C. Storey Stiffness 1) After optimization of RCC structure, storey stiffness decreased by 27.8% as compare to uniform RCC section. 2) In a similar manner, storey stiffness decreased by 37.9% for optimized section of composite structure as compare to uniform composite section. D. Storey Shear 1) Maximum storey shear decreased by 9.1%.for optimized RCC section with respect to uniform RCC section. 2) In a similar manner, maximum storey shear decreased by 13.2% for optimized section of composite structure as compare to uniform composite section. E. Storey Overturning Moment 1) In case of Uniform Section to optimized section for RCC, maximum storey overturning moment decreases by 10.9%. 2) In a similar manner, Uniform Section to optimized section for composite structure, maximum storey overturning moment decreases by 21.5%. F. Future Scope In this paper it is shown that RCC and Composite structures are compared in various aspects under uniform and optimized conditions. But found that Fire protection is very important in case of steel or composite structure. it can lead to change the design criteria such as thickness of slab, nominal cover of composite column etc. and other thing is soil conditions it can be changed other than hard soil and can be compared for worst conditions. in India generally these aspects are not considered fully. But practical applications of these comparison can make structure more safe and more economical. Also, more accurate comparison processes and aspects can be developed. Study can be held on comparison of RCC structure with sear walls and bracing in deferent locations against Composite structure with sear walls and bracing in same location. The researchers can use deferent software and then compare results and state that which software is more effective.
