CH.Gopi chand Civil engineer A PRESENTATION ON ANALYSIS AND DESIGN OF A G+3 RESIDENTIAL BUILDING USING STAAD PRO SRI VENKATESWARA ENGINEERING COLLEGE PRESENTING BY: CH.Gopi chand Civil engineer

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

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

softwares Staad pro staad foundation auto cad

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

What is staad? Structural analysis and design Structure ,analysis, design?

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

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

Alternatives? Robot, SAP200, Struds, FEA software, , SAP and GTSTRUDL

Buildings are be divided into: 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

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.

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

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
