B. Shinde Head, Department of Civil Engineering, Jawaharlal Nehru College of Engineering, Aurangabad, India N.B. Raut ME (Civil), Jawaharlal Nehru College of Engineering, Aurangabad, India ABSTRACT Shear wall is a structural member element to resist the horizontal forces parallel to the plane of wall. Generally they are provided in a high rise building and have been found to be immense use to avoid total collapse of building under the seismic forces. In this paper we have studied the various thicknesses of the shear wall at various heights in same building keeping the positions at the same locations. In this paper study of G+24 story building in zone III Aurangabad region is presented with some investigations which is analyzed by changing the thickness of shear wall at interval of each five story in same building for determining the parameters like drift story, story shear and deflection is done by using SAP 2000 and E Tab. In this project the positions of shear wall are fixed which are provided at the corners of building and at centre portion of building for vertical lift. Key words: Shear wall, ETAB.

International Journal of Civil Engineering and Technology, 7(6), 2016, pp INTRODUCTION In this project we are doing the five models for five different thicknesses of shear wall. The thicknesses are 100 mm, 150 mm, 200 mm, 250 mm and 300 mm. again for each thickness of shear wall there are five models first provided for G+4, G+9, G+14, G+19 and G+24 and determine the parameters like story drifts, story shear and deflection by using SAP 2000 and ETAB by keeping the same position of shear wall then again change thickness of shear wall and checked the above thing for five models editor@iaeme.com

Providing shear walls at corners substantially reduces the displacement due to earthquake, percentage of lateral drift and displacement also. From above result it has been found that thickness increases the stiffness also increases. And also if we increase the height and thickness of shear wall deflection reduces.
