PRESENTING BY:

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

Department of Civil Engineering

ObjectivesThe 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

*

Staad pro staad foundation auto cad softwares*

*SummaryOur graduation project is a residential building in Hyderabad. This building consists of 3 repeated floors.

Structural analysis and design

Structure ,analysis, design?

What is staad?*

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

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

*

Robot, SAP200, Struds, FEA software, , SAP and GTSTRUDLAlternatives?*

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.*

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

*

Wind loadMost 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^2Designed as per IS 875 PART (III)Taking v=50 kmph

**

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
