ABSTRACT:

It is not easy to design a huge building by manually it takes time and manpower too, but by using software it saves time and manpower. The commercial cum residential building has mixed stories, with the ground floor consisting of commercial shops and the first floor consisting of residential floor of 2BHK flat. In big cities, very limited land is available and it is of high cost. The primary goal of our project is to gain sufficient knowledge in planning, design, modeling, and analysis of a commercial cum residential building. In this project, planning and drafting are done by using Autodesk AutoCAD, 3D Modeling is done by using Autodesk Revit Architecture, and Analysis and Design are done by using StaadPRO.V8i. Manual calculations of structural members like Slab, Beam, Column, and footing are done by the Limit State Method by using IS456:2000, IS875 and design aid SP16 code.

KEYWORDS- Autodesk AutoCAD, Autodesk Revit Architecture, StaadPRO.V8i, Planning, Design, Modeling, analysis.

1. INTRODUCTION:

Our project is “Design and modeling of commercial and Residential Building by using Autodesk Revit Architecture andStaadPRO.”Themainobjectiveofourprojectistogain sufficient Knowledge in planning, Design, Modeling and Analysis of a commercial cum residential building. It is a reinforcedconcreteframedstructureconsistingofG+1.All the structural members are designed by using National Building Code. IS 456:2000, IS 875, and design aid SP16. The structural components like Slab, Beam, Column and footing are manually designed by using Limit State Method.

Materials were used as specified by the National Building Code. For all the design, Concrete M20 grade and Fe 500 steelbars.BrickwallsareinC.M1:5mixwithwallexternal and internal wall thickness of 230 mm and 150 mm

respectively.Thetotalareaofourbuildingis139sq.m.The commercial shops had a glass wall for shops. Commercial space includes three shops, Two Store rooms, One Staffroom and two separate toilets for male as well as female and a staircase of 3 m wide. First floor is a residentialfloor(2BHK)withallthefacilities.

LITERATURE REVIEW-

1. V. S. Nagasai et al. (2019), “Planning, Analysis and DesignofResidentialBuilding(G+5)ByusingSTAAD Pro.” This paper deals with Frame analysis, which was done by STAAD.pro. Slab and beams were designed as per IS code 456 2000. The properties such as shear, deflection, development, torsions are definedbytheIScodeprovisions.

2. Falak Vats (2019), “Review paper on design and analysis of multi storey building by the use of Stadd.Pro,” He concluded that Stadd.Pro provides a much faster approach to structural analysis and designwithachancesofminimumerrors.Therehas been several research conducted comparing the results from Stadd.Pro to the manually calculated results, which all support the use of Stadd.Pro over manual the one. Stadd.Pro is a much better way to analyse complicated load combinations and is quite versatile.

concluded for the uses of scheduling and cost estimating in Autodesk Revit respectively, and provided a case study to show how Autodesk Revit can work for Architects, Engineers and contractors. As well as comparing Autodesk Revit Estimate with ManualEstimate.

5. Amar Hugar et al. (2016), has been discussed that the Computer Aided Design of Residential Building involves scrutiny of building using STAAD.Pro and a physical design of the structure. Traditional method of study show tedious calculations, and such tests are time consuming task. Analysis is made quickly byusingsoftware.Thisprojectcompletelydealswith scrutiny of the building using the software STAAD.Pro. Finally, the results are compared with physical calculations. The elements are created as perIS:456 2000.

6. Bandipati Anup et al. (2016), thispaperdealswith evaluating and planing a multi storeyed building [G + 2 (3 dimensional frame)] adopting STAAD Pro. The technique used in STAAD.Pro is limit state technique.Initiallytheyhavecreated2 Dframesand cross checked with manual calculations.They tested and created a G + 2 storey building [2 D Frame] instantlyforallfeasibleloadcombinations.Thework has been finished with some more multi storyed 2 Dimensional and 3 Dimensional frames beneath variousloadcombinations.

4.1 DESIGN USING AUTOCAD

AutoCAD is a computer aided design and drafting software application. AutoCAD is used to draft out plans, elevations, cross sections etc. of a building. The CAD drawing helps to identify the details such as balcony, kitchen, rooms, dining hall, thickness of wall, sitedetailsetc.

4.3 STAAD ANALYSIS AND MODELING

STAADPROisoneofthemostpopularsoftwarethatis used for analysis and designing towers, bridges, buildings etc.The first step in our process will be reading the plan that has been created. From this readingprocess,wewillgetalltheinformationsuchas the number of storeys, number of bays, loadings, etc. The G+1 building is modelled using the Structure WizardinsideSTAADProaccordingtothebuilding.

4.3.1 DEAD LOAD

20.0KN/m

Dead loads are the structural loads that include the self weight of the structural members such as walls, ceilings,floors,plasteretc.AccordingtoIS875part2,

Deadload 15KN/M

Self weight is the body’s own weight of body, due to the mass present in it. In STAAD Pro, we can directly add the self weight by selecting the whole structure and simply specifying the direction of force. It is a dead load. AccordingtoIS875part2,

Selfweight Factor= 1KN/M

4.3.2 LIVE LOAD

Live loads are temporary loads that are applied to the structure on and off over the life of the structure. AccordingtoIS875part2,
