- Prepare a Design Basis Report for the project
- Create structural model using STAAD Pro Connect Edition
- Prepare DL, LL, WL and EQL load calculations as per IS 875 standards
- Design slab element using MS – Excel
- Design beam and column element using STAAD RCDC. Attach the design calculation report.
- Design Foundations using STAAD Foundation.
- Prepare bar bending schedule for beam and column using STAAD RCDC
Attach necessary sketches and drawings wherever required.
All stipulations, assumptions and design parameter must adhere to Indian Standards.
1. Prepare a Design Basis Report for the project
Design Basis Report is attached in .docx format.
2. Create structural model using STAAD Pro Connect Edition
Open the Structural wizard
Select Frame model> Bay frame
Enter the required parameters:
Length = 25m
Height = 24.5m
Width = 16m
No. of bays along length = 5
No. of bays along height = 7
No. of bays along width = 4
Assign property Assign material Assign supports
Go to property section
Click on Define material
Select the section> Rectangular
Select the material type> concrete
For the rectangular section enter YD & ZD in column below
Click add and close
Select the material type and assign to the selected view for the support
Click on the support
Click on create
Select type of support do we want to assign the section
Click on add close
Assign loads
To assign loads go to the loading tab
Add definitions (Wind, Seismic etc.)
Add load cases details as per the requirement (viz. DL, LL, EQ etc.)
Select the load type and add the loads (viz. Member load, self-weight etc.)
Select the members and assign the designated load
Go to the Loading tab> Definitions> Seismic Definition
Click on New, select the seismic code and assign the seismic parameters
Then click on Add and provide the floor weights as calculated in the previous question
After adding the floor weights, go to Load Cases Details> Add
Add the seismic loads in X and Z direction
Specify Type of Analysis
Run Analysis
3. Prepare DL, LL, WL and EQL load calculations as per IS 875 standards
Dead Load
Assuming 150mm thick slab thickness
Dead load of slab = Unit weight of concrete x slab thickness
= 25 x 0.15
Dead load of slab = 3.75kN/m2
Dead Load of beams
Considering the beams of cross-section 300 x 500 mm.
Dead load of beams = Unit weight of concrete x cross section of beam
=25 x 0.3 x 0.5
= 3.75kN/m ≈ 4kN/m
Dead load of beams = 4kN/m
Superimposed loads of partition walls
Assuming 230 mm thick brickwork.
Height of the brickwork = floor height = 3.5m
Therefore,
Dead load of brick masonry partition = Unit weight of masonry brick x wall dimension
18 x 3.5 x 0.23 = 14.49 kN/m ≈ 15kN/m
Superimposed loads of partition walls = 15kN/m
Live Load
As the proposed project is a hospital building, the IS 875 PART 3 states different live load values for different rooms within a hospital that are listed below:
|
OCCUPANCY |
LIVE LOAD kN/m2 |
|
All rooms and kitchen |
2.0 |
|
Toilets and Bathrooms |
2.0 |
|
Balconies |
3.0 |
|
Corridor, Passages |
3.0 |
4. Design slab element using MS – Excel
