Project 1

AIM:

• To design a multi-storey Residential Building located in Bangalore using STAAD Pro Connect Edition

PROCEDURES AND DETAIL:

1. Design a multi-storey Residential Building located in Bangalore using STAAD Pro Connect Edition. The specification must be as follows:

Building floors	G + 6 + R
Plan dimension	B = 25m ,  L = 16m
Storey Height	h = 3.5m
Soil	Hard soil
Use	Residential Purpose
Safe Bearing Capacity	180 kN/m2
Maximum slab thickness	150mm

Assume suitable sections for structural elements. Follow IS456, IS1893 and IS 875

1. Prepare a Design Basis Report for the project
2. Create structural model using STAAD Pro Connect Edition
3. Prepare DL, LL, WL and EQL load calculations as per IS 875 standards
4. Design slab element using MS – Excel
5. Design beam and column element using STAAD RCDC. Attach the design calculation report.
6. Design Foundations using STAAD Foundation.
7. Prepare bar bending schedule for beam and column using STAAD RCDC
8. Attach necessary sketches and drawings wherever required.
9. All stipulations, assumptions and design parameter must adhere to Indian Standards.

Unit weight of the materials

• Reinforced Cement Concrete = 25">2525 kN/m3">kN/m3kN/m3
• Plain Cement Concrete = 24">2424 kN/m3">kN/m3kN/m3
• Cement Concrete Screed = 20">2020 kN/m3">kN/m3kN/m3
• Cement Masonry Units = 22">2222 kN/m3">kN/m3kN/m3
• Structural Steel = 78.5">78.578.5 kN/m3">kN/m3kN/m3
• Soil = 18">1818 kN/m3">kN/m3kN/m3

Dead Load

Floor slab 

• Slab weight = 3.75">3.753.75 kN/m2">kN/m2kN/m2 (0.15m×25kN/m3)">(0.15m×25kN/m3)
• Partitions = 1.5">1.51.5 kN/m2">kN/m2kN/m2
• Floor Finish = 2.5">2.52.5 kN/m2">kN/m2kN/m2
• Miscellaneous = 1">11 kN/m2">kN/m2kN/m2

Total Floor Load = 8.75 kN/m2">kN/m2

Roof slab

• Slab weight = 3.75">3.753.75 kN/m2">kN/m2kN/m2 (0.15m×25kN/m3)">(0.15m×25kN/m3)
• Insulaions and Water Proofing = 0.5">0.50.5 kN/m2">kN/m2kN/m2
• MEP Services = 0.5">0.50.5 kN/m2">kN/m2kN/m2
• Miscellaneous = 0.5">0.50.5 kN/m2">kN/m2kN/m2

Total Roof Load = 5.25 kN/m2">kN/m2kN/m2

Live Load

Floor slab 

• Common Corridor = 3">33 kN/m2">kN/m2kN/m2

Total Floor Load = 3 kN/m2">kN/m2kN/m2

Roof slab

• Accessible Roof = 1.5">1.51.5 kN/m2">kN/m2kN/m2

Total Roof Load = 1.5 kN/m2">kN/m2

Result:

• Thus multi-storey Residential Building located in Bangalore using STAAD Pro Connect Edition is been designed
