Abstract

High-rise structures are becoming quite common everywhere because of the increasing population and less land area. Generally, High-rise buildings are constructed of RCC, but in RCC buildings due to the bulky size of components of the structure self-weight will be more due to the heavy density of the material. After observing such difficulties, we have come up with the idea of a Steel-Concrete Composite Structure. The composite structure consists of composite columns, beams, and a deck slab which is connected with shear connectors. In this project, the comparative study of f performance of RCC and Composite structure shall be done. The composite structure consists of structural steel and concrete which may provide more ductility and flexibility to the structure and hence it may perform well during an earthquake. The modeling and analysis of the structure shall be done using ETAB software and the parameters like base shear, story drift, displacement, stiffness, strength, period, etc. shall be compared

Introduction

I. INTRODUCTION

The Structure, which is constructed using Different Materials such as Concrete, Steel, Stone, Brick, Block, and Timber is known as a Composite Structure. The Proper Combination of any two of these Materials is made and the Composite Structure is Constructed. This Paper includes an analysis and Comparison of G+10 Symmetric

R.C.C Structure with G+10 Symmetric Composite Structure and G+10 Unsymmetric R.C.C Structure with G+10 Unsymmetric Composite Structure. This Structure is situated in Earthquake Zone III. The analysis is done by Equivalent Static Method and Response Spectrum Method in ETABS 18. The analysis of Earthquake Loading is Carried out by Using IS-1893-2016. The different Parameters like base shear, story drift, displacement, stiffness, strength, and are Compared to the RCC structure and Composite Structure.

 

II. ADVANTAGES OF COMPOSITE COLUMNS

  1. It has great fire and corrosion resistance in concrete-encased columns.
  2. Composite columns are Economic over the conventional use of structural steel or reinforced concrete.
  3. It increases the available usable floor-to-floor height for a given strength.
  4. Drying shrinkage is a smaller part of composite members than ordinary conventional reinforced concrete.
  5. Outer dimensions of the column over several floors are constant. So, architecture detailing and construction becomes easy.

III. ADVANTAGES OF COMPOSITE BEAMS

  1. The depth and weight of the beam requirement are less so that construction depth also reduces by-product to increase the headroom of the building.
  2. The higher Stiffness in composite beams leads to less deflection.
  3. The span of the slab can be more by using Composite Beams without using any intermediate columns.
  4. The beam which is encased has higher resistance against fire and corrosion.
  5. The speed of construction became fast by using the composite beam.
  6. Concrete and Steel both are utilized properly in the composite structure.

IV. LITERATUREARE REVIEW

A. Seismic Performance Of Rc Buildings With Shear Wall

In this study, it has been observed that with the inclusion of infill panels and shear walls, the strength and rigidity of the frame structure were found increasing and neglecting them in the analysis and design of the structure will lead to failure due to stiffness irregularity.

Author: Mohd Danish, Mohd Shariq.

B. Analysis Of RC Structure With And Without Shear Wall And Optimum Location Of Shear Wall

Here is to conclude that story displacement for structures with a shear wall at corners is less as compared to that of structures with a shear wall at the Centre and a structure without a shear wall. Hence it is feasible to provide a shear wall at corners. At last, we can observe that structure with shear walls at corners gives better results as in the case of the other two structures.

C. History, Concept, and Types of Composite Columns

This method will be the future of construction in developing countries like India because this technique provides more strength as compared to normal RCC sections of the same cross-sectional area. This technique also reduces the cost and time of construction.

D. Chhatrapati Shivaji International Airport- Integrated Terminal Building

Composite Columns leads to a smaller number of column section which gives a bigger clear span and economical advantage.

E. Installation & Placement of Composite Floor Decking

Decking with embossed ribs to develop a mechanical shear bond with concrete. Ends are die-set for a neat fit and side laps are interlocking.

Author: Saddam M. Ahmed

V. COMPOSITE STRUCTURE CONNECTION DETAILS

Concrete with steel composite column is a full compression type member, which has major two types concrete encased in steel section and concrete infilled tube steel section and it is usually used as a load bearing Members in a   composite frame.   

Because of   big construction and high-rise buildings of 15 and above, the size of columns increases because of the revised IS codes and FSI. In some cases, the size of columns increases too much in RCC structures of more than 1m. For this type of problem, Composite columns are the best solution.

A. Shear Connector

Shear connectors connected on the top flange of the steel girders provide the composite action between the steel girders and slab, increasing both stiffness and strength. This kind of arrangement plays an important role in the seismic response of a structure. A major element of composite structure: 1. Composite column 2. Composite Beam 3. Deck slab 4. Shear Connectors Major elements of Shear Connector: 1. Perfobond ribs 2. Oscillating Perfobond strips 3. Waveform Strips 4. Channel connector 5. Pyramidal Shear Connectors 6. Rectangular Shaped Collar Connectors.

Conclusion

By using a Composite Structure overall weight of the structure is reduced in composite structure so that shear at the base is less. So, in earthquake-affected areas performance of the composite structure is better. We have observed that R.C.C structures are more likely to overturn during an earthquake compare to the composite structure. So, in this case, also composite structures are more suitable. Around 90% of Structural Steel can be recovered and reused for the composite structure. In terms of cost, Composite Structures are more economical than R.C.C. structures.
