Design and analasys of a g+3 residential building using staad

  1. 1. 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
  2. 2. ANALYSIS ANd deSIgN of (g+3) ReSIdeNTIAL BUILdINg USINg STAAd By CH.Gopichand Department of Civil Engineering
  3. 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 3

  5. 5. Summary Our graduation project is a residential building in Hyderabad. This building consists of 3 repeated floors. 5
  6. 6. What is staad?  Structural  Structure analysis and design ,analysis, design? 7
  7. 7. Advantages? Analysis and design of rcc, steel, foundations, bridges etc. 8
  8. 8. Why staad?  An hour  For a building with several beams and columns?  At least a week. 9
  9. 9. Alternatives?  Robot, SAP200, Struds, FEA software, , SAP and GTSTRUDL 10
  10. 10. 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

  27. 27. 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. 32
  28. 28. 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 3333
  29. 29. Lateral forces  High wind pressures on the sides of tall buildings produce base shear and overturning moments.   These forces cause horizontal deflection  Horizontal drift deflection at the top of a building is called is measured by drift index, ∆/h, where, ∆ is the horizontal deflection at top of the building and h is the height of the building  Drift  3434
