With development of country, development ofresidential buildings takes place. In this paper the planning of residentialbuilding is completed with limit state analysis. Limit state method may be agreat way to achieve strength of structure with low cost when compare toother design synopsis. The modelling and analysis of the structure is done byusing STAAD. Pro 2007, and the designing was done manually. Practicalknowledge is an important and vital skill required by every engineer. Then thedesign follows with different types of loading conditions with different casesof rooms and position of rooms. The Plan is made by AUTOCAD 2018. Afterplotting the design, analysis is made with the help of STAAD Pro software andthe results found out to be same.How to cite this paper: Ankur Chauhan Sukrit Jain Raghav Kumar Tiwary"Analysis and Design of ResidentialBuilding (G 1) using STAAD Pro"PublishedinInternational Journalof Trend in ScientificResearchandDevelopment(ijtsrd), ISSN: 24566470, Volume-4 ijtsrd.com/papers/ijtsrd33310.pdfKEYWORDS: STAAD Pro, Residential Building, AUTOCADCopyright 2020 by author(s) andInternational Journal of Trend in ScientificResearch and Development Journal.

From times immemorial man has beenattempting endeavors in enhancing their way of life. Thepurpose of his endeavors has been to give a monetary andproductive sanctuary. The ownership of safe house otherthan being a fundamental, utilized, gives a sentimentsecurity, obligation and demonstrated the societal positionof man.Each individual has an inborn enjoying for a quiet domainrequired for his charming living, this item is accomplished byhaving a position of living arranged at the safe andadvantageous area, such a spot for agreeable and wonderfulliving requires considered and kept in stand point. A Peaceful domain Security from all normal source and atmosphereconditions General facilities for group of his neighborhoodThe basic requirement for a man is to reduce the cost ofconstruction. The limit state method is use.@ IJTSRD Unique Paper ID – IJTSRD33310 II.EXPERIMENTAL SETUPThe main aim of this project is to style a residential buildingwith appropriate reinforcement as per Indian standards withlimit state analysis. The design of residential building takesgeneration of plan which is completed with the assistance ofAUTOCAD software. Before browsing this software therespective positions of rooms (like kitchen, dining hall,master bedrooms, utensils etc). The positioning of rooms isdone with respect to aspects of building.A.Arrangements of Rooms1. AspectsAspect means particular arrangement of doors and windowsin external walls of residential building while environmentto undergo it. The important aspect in panning is not onlyproviding the sunshine but also hygiene and eco-friendlyenvironment. The room is based upon the allowance of airand light and referred to such particular aspect. As per theplan the different arrangements of room are shown below.Volume – 4 Issue – 6 September-October 2020Page 233

In working statemethod which is broadly followed in our country has factorof safety of 3 for concrete and 1.7 for steel it means 200%more concrete and 70% more steel.The amount of more concrete and steel, bigger areas can beseen in working stress method. As we can reduce out area byfollowing limit state method and hence also proved aseconomical.The design review the study of AUTOCAD 2018 and analysiswith STAAD pro and found out the structure is safe indeflections, stresses, loads and moments.@ IJTSRD Unique Paper ID – IJTSRD33310 The aspects and prospects are made according to NBC ofIndia, which gives various advantages over randomarrangements.REFERENCES[1] IS: 456 2000, “Plain and Reinforced concrete”[2] IS: 875 1987, “Part 1 & 2 for dead and live loads”[3] Design of column charts, “SP:16 1980”[4] Aspects, Prospects and Sizes, “National building code ofIndia”.[5] Design of beams, columns, slab and footing BOOK,“Limit state design by A.K.Jain”.[6] Design of columns, stair cases, “Reinforced concretestructures by B.C.Punmia”.[7] https://www.academia.edu/20157844/Design of Residential Building and Analysis with STAAD ProVolume – 4 Issue – 6 September-October 2020Page 243
