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. 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

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
