New M.Tech. Thesis Submitted from civil


Shear wall is a structural system composed of braced panels (also known as shear panels) to counter the effects of lateral load acting on a structure. Wind and seismic loads are the most common loads that shear walls are designed to carry. Shear walls resist in-plane loads that are applied along its height. A diaphragm, collector, or drag member generally transfers the applied load to the wall. They are built in wood, concrete, and CMU (masonry). Shear walls must provide the necessary lateral strength to resist horizontal earthquake forces. The present thesis is made in the interest of studying and analysis of various research works involved in enhancement of shear walls and their behavior towards lateral loads. As shear walls resists major portions of lateral loads in the lower portion of the buildings and the frame supports the lateral loads in the upper portions of building, which is suited for soft storey high-rise building, as in India base floors used for parking and garages or officers and upper floors are used for residential purposes. Shear wall is designed in a high-rise building and in earthquakes prone areas. In this research, the shear wall is analyzed by using SAP 2000 software. The main function of shear wall is to resist lateral force acting on the structure by acting like a deep beam. Normally they are located inside building and mostly walls that support lift is reinforced to act as shear walls. Linear and Nonlinear Analysis is done which includes various load combination based on the Indian Code provisions i.e. IS standard (IS 875 (PART I & PART II) – 1987) and Seismic load as per as IS standard IS 1893 PART I – 2007 and IS 456- 2000. This report includes various chapter in which applied to putting together of G+10 floor situated in ZONE IV in Ludhiana. Shear force, bending moment and floor drift be computed and location of shear wall with heights and types would be found. For this study, 11-storey building with a 3.2 -meters height for each storey, regular in the plan is modeled. These buildings are designed in keeping with the Indian Code. The buildings are assumed to be fixed at the base. The sections of structural elements are rectangular. Storey heights of buildings are assumed constant including the ground storey. Five different models are studied with different positioning of the shear wall in the building. Models are studied in zone IV comparing lateral displacement for all models.
