Master's Thesis from the year 2014 in the subject Engineering - Civil Engineering, grade: 8.37, Andhra University, course: Master's Degree, language: English, abstract: The study mainly aims to determine a solution for shear wall location in a multi-storey building based on the response spectrum method using ETABS. In this study, two multi-storied buildings, one of six and other of thirteen stories have been modeled for an earthquake zone V in India using the response spectrum method as per IS: 1893 (Part 1) -2002. Five different models of the varying position of shear walls are considered for studying their effectiveness in resisting lateral forces. The work also deals with the effect of the variation of the building height on the structural response of the shear wall. Lateral displacements, storey shear, storey bending moment and storey drift were computed in all the cases and location of the shear wall was established based upon the above computations.

Right from the evolution of the earth, earthquakes have been a cause of great disasters in the form of destruction of property, injury, and loss of life to the population. The effective design and construction of earthquake-resistant structures has much greater importance in this country due to the rapid industrial development and concentration of the population in cities. Recently there has been a considerable increase in the construction of tall buildings both residential and commercial and the modern trend is towards more tall and slender structures. Thus, the effect of lateral loads like wind loads, earthquake loads and blast forces is attaining increasing importance and almost every designer is facing the problems of providing adequate strength and stability against lateral loads. Now the situation is quite different and a clear understanding of the effect of the lateral loads on the building and the behavior of various components under these loads is essential.

Shear wall systems are one of the most used lateral load resisting systems in high-rise buildings. Shear walls have very high in-plane stiffness and strength, which can be used to simultaneously resist large horizontal loads and support gravity loads, making them quite advantageous in many structural engineering applications. It is very necessary to determine the effective, efficient, and ideal location of the shear wall.
