1. SRI VENKATESWARA ENGINEERING COLLEGE A PRESENTATION ONANALYSIS AND DESIGN OF A G+3 RESIDENTIAL BUILDING USING STAAD PRO PRESENTINGBY: CH.Gopichand Civil engineer

2. ANALYSIS and design of (g+3) RESIDENTIAL BUILDING using staad By CH.Gopichand Department of Civil Engineering

3. Objectives The Objectives of the Project are:- • Carrying out a complete analysis and design of the main structural elements of a multi-storey building including slabs, columns, shear walls. • Getting familiar with structural soft wares ( Staad Pro ,AutoCAD) • Getting real life experience with engineering practices

4. softwares Staad pro staad foundation auto cad

5. Summary Our graduation project is a residential building in Hyderabad. This building consists of 3 repeated floors.

7. What is staad? • Structural analysis and design • Structure ,analysis, design?

8. Advantages? • Analysis and design of rcc, steel, foundations, bridges etc.

9. Why staad? • An hour • For a building with several beams and columns? • At least a week.

10. Alternatives? • Robot, SAP200, Struds, FEA software, , SAP and GTSTRUDL

11. Types of buildings • Buildings are be divided into: • Apartment building • Apartment buildings are multi-story buildings where three or more residences are contained within one structure. • Office building • The primary purpose of an office building is to provide a workplace and working environment for administrative workers. 11

32. wind load • The amount of wind load is dependent on the • following: • • Geographical location, • • The height of structure, • • Type of surrounding physical environment, • • The shape of structure, • • Size of the building.

33. Wind load • Most important factor that determines the design of tall buildings over 5 storeys, where storey height approximately lies between 2.7 – 3.0 m • P=k1*k2*k3*vz^2 • Designed as per IS 875 PART (III) • Taking v=50 kmph 33

34. Lateral forces • High wind pressures on the sides of tall buildings produce base shear and overturning moments. • These forces cause horizontal deflection • Horizontal deflection at the top of a building is called drift • Drift is measured by drift index, /h, where,  is the horizontal deflection at top of the building and h is the height of the building 34
