---------------------------------------------------------------------***--------------------------------------------------------------------Abstract- The main task of structural engineers is to determine a structure's behavior in the presence of horizontal forces. Tall structures need to be strong enough to resist horizontal pressures brought on by tremors and wind. Shear walls are utilized to enhance the structure's rigidity to counteract horizontal forces. A device called a tuned mass damper is fastened to a structure and is made up of a mass, a spring, and a damper. Its purpose is to reduce the dynamic response of the structure. Response Spectrum Analysis will look at the employment of tuned mass dampers and shear walls in different places in a G+20 multi-story residential building. In a multi-story structure with G+20, base shear and the maximum allowable displacement are examined in this work. Seismic zones established by IS 1893 in India, Etabs 2018, a popular FEM integrated software, is used for the study and modelling of the complete structure. This project uses type II (medium soil) soil to do a dynamic analysis for an unsymmetrical construction layout in four zones. The findings indicate that the structure with tuned mass damper and shear walls (i.e., model 3) will exhibit better results in terms of all seismic parameters when compared to the structures without shear walls (i.e., model 1) and with shear walls (i.e., model 2).
These days, high-rise structures, commonly referred to as skyscrapers, are highly sought after because of their many advantages, which include the capacity to maximize space while taking up little land. They're also really lovely. These buildings are very challenging to design, and building them requires engineers to overcome several challenges. Although a number of factors are taken into account during the design process, the main goal of this project is to use a shear wall with damper to create a 21-story structure and compare the results to a standard building of the same height that has both a shear wall and a damper. The building design made use of the following structural element, which will be covered in greater depth later. The components that are utilized in this project are ● ●

2. To ascertain the behavior of a construction having a shear wall.
1.INTRODUCTION
3. Shear wall and tuned mass damper analysis of the structure.
Because of the fast-growing industrialization and population boom of the 21st century, there is an increasing need for building construction, which presents an intense challenge for engineers to analyze, create, and design new types of structures, particularly in seismic zones. These natural catastrophes will be extremely difficult for civilization to handle and will have a significant impact. Therefore, engineers must build seismic-resistant buildings in this zone to counteract the seismic power and minimize its impact as much as possible in order to deal with this. Although no construction can be completely earthquake resistant—as we all know—by creating it, the power of the seismic forces may be reduced, minimizing the harm to people.

4. For each of the aforementioned three scenarios, a comparative analysis of base shear, storey displacement, fundamental natural period, frequency, and storey drift has been conducted for distinct seismic zones. 1.2 Shear wall: A shear wall is a structural element used to resist lateral forces, such as those caused by wind or seismic activity. Typically made of reinforced concrete or masonry, shear walls are designed to provide stability and strength to a building, preventing excessive swaying and ensuring it can withstand various loads.
