Many design company’s usethis software for their project design purpose. So, this paper mainly deals with the comparativeanalysis of the results obtained from the analysis of a multi storied building structure whenanalysed manually and using ETABS software.Structural response to earthquake depends on Dynamic characteristics of the structures andintensity, duration and frequency content of existing ground motion. Structural analysis meansdetermination of the general shape and all the specific dimensions of a particular structure sothat it perform the function for which it is created and will safely withstand the influences whichwill act on it throughout its useful or@iaeme.com

C.V.S. Lavanya, Emily.P.Pailey, Md. Mansha Sabreen and U.P.B.C. SekharThe effective design and construction of a earthquake resistant structures have greatimportance all over the world. Geographical statistics of India show that almost 54% of theland is vulnerable to earthquakes. This project presents analysis and design if multi storiedresidential building using ETABS software with lateral loading effect of Earthquake. Thisproject is designed as per INDIAN CODES- IS 1893-part2:2002, IS 456:2000. This analysis iscarried out by considering severe seismic zones and behaviour is assessed by taking type-IISoil condition. In our project we are considering a plan under zone –IV. Seismic Intensity isSevere and Zone Factor is 0.24 at Panaji. The building is proposed to have Ordinary RCmoment-resisting frame and the Response Reduction Factor(R) is 3.0Design example of a six story building:In this paper, from the plinth to the certain height of the building the column size may differthat is it would be more when compared to the upper columns because to reduce the failure inthe structure. The diaphragm is rigid. The main beams rest on the columns to avoid localeccentricity.Comparison of analysis and design of regular and irregular configuration of multi storiedbuilding in various seismic zones using ETABS software.The centre of mass is the unique point at the centre of a distribution of mass in space. Thecentre of mass is the mean location of a distribution of mass in space.Seismic Analysis of Multi-storeyed Building:As this project deals with the most economical column method in this project we havedesign the structure in an economical way by reducing the sizes in the sections. As the load ismore at the bottom when compared to the top floors, there is no need of providing large sizesat the top. Economizing the column by means of column orientation is longer span longerdirection will reduce the amount of bending as a result there are of the steel is reduced.3.

Analysis and Design of G 4 Residential Building Using ETABSFigure 1 Centre Line Diagram3.4. Material PropertiesTo carry out the work in ETABS software the properties of the materials such as concrete andsteel should be defined. Similarly the loads should be defined such as live load, super deadloads.Grade of concrete: M20Grade of steel: Fe 415Live loads: 2kN/m2SDL (floor finish): 1.5kN/m2SDL (wall loads inner and outer respectively): 6.21kN/m2 and 12.45kN/m2Beam size: 230mm x 450mmColumn size: 230mm x 450mm3.5. Description of Loads All moving loads come under live loads.Live load (on floors): 2kN/m2, (IS 875:1987 – Part -2)Live load (on roof): 1kN/m2, (IS 875:1987 – Part -2) Floor finishes are the super imposed dead loads.Floor Finishes (on floors): 1.5kN/m2Floor Finishes (on roof): 2kN/m2 Wall loads are the loads of bricks used in construction.For 9” wall (outer wall): 12.45kN/m2 (wall thickness*height of the floor*density of brick 7editor@iaeme.com

Our project deals with provision of earthquake resistant structure which is also economic.2. Minimum sizes of the beams and columns were provided as B230mmX450mm andC230mmX450 mm, after analysis only the failed column axes and dimensions were changed toC230mmX750 mm which comes under economic.3. Seismic analysis was done by using ETABS software and successfully verified manually as perIS 1893-2002.4. There is a gradual increase in the value of lateral forces from bottom floor to top floor insoftware analysis.5. Maximum Shear force is 93.8KN and Maximum Bending Moment values is 79.5KN, which isacted at top floor of the building.REFERENCES[1][2][3][4][5][6][7]Mahesh N. Patil, Yogesh N.
