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.

ANSWER:

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

Procedure:-

Unit weight of the materials

Reinforced Cement Concrete = 2525 kN/m3kN/m3

Plain Cement Concrete = 2424 kN/m3kN/m3

Cement Concrete Screed = 2020 kN/m3kN/m3

Cement Masonry Units = 2222 kN/m3kN/m3

Structural Steel = 78.578.5 kN/m3kN/m3

Soil = 1818 kN/m3kN/m3

Dead Load:

Floor slab

Slab weight = 3.753.75 kN/m2kN/m2 (0.15m×25kN/m3)(0.15m×25kN/m3)

Partitions = 1.51.5 kN/m2kN/m2

Floor Finish = 2.52.5 kN/m2kN/m2

Miscellaneous = 11 kN/m2kN/m2

Total Floor Load = 8.75 kN/m2

Roof slab

Slab weight = 3.753.75 kN/m2kN/m2 (0.15m×25kN/m3)(0.15m×25kN/m3)

Insulaions and Water Proofing = 0.50.5 kN/m2kN/m2

MEP Services = 0.50.5 kN/m2kN/m2

Miscellaneous = 0.50.5 kN/m2kN/m2

Total Roof Load = 5.25 kN/m2kN/m2

Live Load:

Floor slab

Common Corridor = 33 kN/m2kN/m2

Total Floor Load = 3 kN/m2kN/m2

Roof slab

Accessible Roof = 1.51.5 kN/m2kN/m2

Total Roof Load = 1.5 kN/m2

DESIGN OF SLAB:

BEAM CALCULATION:

WIND LOAD CALCULATION:

RESULTS:

SEISMIC LOAD CALCULATION:

LOAD PARAMETERS:

• After going to analyse and design tab we have selected the concrete design hole structure and then select the code as IS 456

• After selecting the code now select the perimeters select all the perimeters and press okay

• The design parameters should be given according to the material requirements given below

• Now define the parameters such as clear, compressive strength of concrete , yield strength of main reforcement steel, yield strength of share reforcement

• Also add design beam and design colum perimeters and assign it to the structure

• Now go to the command and analyse the structure and select the utility option and click on the analyse output for the results
