getting higher and higher. The way these structures perform is significantly impacted by the impact of lateral loads from wind and earthquakes. Structural engineers frequently substitute shear walls for columns in their designs. Though they do a great job of resisting lateral shear, the shear walls frequently cause the structure to become unduly stiff. Although columns increase a structure's ductility, they frequently cannot withstand the full shear. As a result, choosing the appropriate ratio of shear walls to columns for structures of a given height becomes essential. Many models have been analyzed in ETABS and STAAD PRO software with different conditions of shear wall position, shapes, soil types, and seismic zones, all of which have an effect of dead load, live load, seismic load, and wind load.
Various types of irregularities: 1. Vertical stiffness irregularity, 2. mass irregularity, 3.in plan irregularity, 3.out of plan irregularity, 4. vertical geometry irregularity, 5. discontinuity irregularity, 6. torsional irregularity, 7.non orthogonal irregularity. Brief introduction about antilia: Two US architecture firms, Hirsch Bedner Associates in Los Angeles and Perkins & Will in Chicago, designed the building. The building was designed to withstand a magnitude 8 earthquake.[6] The top six floors are private areas. The design of the house includes flowers and the sun. Following Nita Dalal Ambani's admiration for the modern Asian interiors at the Mandarin Oriental, New York, which were also created by them, they were consulted. The building has a total of 27 floors, a height of 173 meters (568 feet), an area of more than 6,070 square meters (65,340 square feet) and 168 - parking, a restaurant and 9 elevators, a theatre for 50 people, a garden with a terrace, a swimming pool, a spa, health centre, temple and an igloo with snowflakes falling from its walls.
Key Words: tall irregular Structure, shear wall, Seismic Load, E-tabs, Staad pro.
1.INTRODUCTION Taller buildings are preferred these days due to the fast urban population growth, limited amount of available land and high cost of available land. Lateral load becomes increasingly significant as a structure's height increases. Wind load and seismic load are also significant factors in tall structures. Shear wall systems and diagrid structural systems have recently become the most common used lateral load resisting systems. Shear walls have very high plane stiffness and strength, allowing them to resist large horizontal loads while also supporting gravity loads, making them very useful in many structural engineering applications. An earthquake is a variation in ground vibrations. Unpredictable earthquakes can happen at any time or place, and our nation has had numerous earthquakes that have severely damaged buildings and claimed lives. Therefore, the building must be designed by the design engineers to be resistant to damage brought on by the effects of seismic actions. These experiences have shown the latest advancements in strengthening the resistance to seismic actions, and proper execution of those actions is necessary to prevent damages from earthquakes. Shear walls are an excellent method of providing earthquake resistance to multistorey reinforced concrete structures. The structure is still damaged as result of one or more earthquakes. The
