Week 2 Challenge
AIM :
1.1 How will you assign Circular section to column?
Introduction :
- Column are the vertical member in the Structure that can be of varing size in dimesions
- The circular section of column are provided at the upper floor of the building for the better load carrying and access purpose
Procedure :
- Create the model in the staad pro that can be a column
- Go to properties in that Define paramters
- Assign the circular shape of the column
- The radious of the circular is given
1.2 : How will you assign Unit system to a .std model file?
ANS :
- To Assignt unit system in the staad pro
- Go to file menu and then settings
- open the structural settings
- Change the dimesions as the required units
1.3: What are the parameters to be specified while using “Bay Frame” option?
ANS :
- To create the parameter of the design by Bay frame
- By clicking on the Structural wizard option
- Click on the frame model option
- click on the Bay frmae option
- Enter the parameters like the lenght , breadth , height and the bay frame along the length , breadth and height
1.4: Name few codal standards incorporated in STAAD Pro software.
ANS:
- In Staad pro the Codal standard are incorported for the Steel , Concrerte , Aluminium.
- For the Steel the codal provision are IS 800 , IS 800 : 2007 , IS 800:2007 WSD , IS 801
- For the concrete the Codal provision are the IS 456 and IS 13920 for the Sismic Design
1.5: How will you specify the design compressive strength for a RCC section?
ANS :
- Go to the Design option
- Click on the define parameter
- In the design Parameter the FYLD Compressive strength of RCC section is Given as 25000 KNm
2:1: State the “Input” steps involved in RCC design.
ANS:
Steps Involved in RCC design are
1. Geometry : The Node loaction and the node spacing are given
2. Properties : Specify the Sectional properties of the section
3. materials : Specify the properties of the material
4. Specifications : The pecifictions are given
5. Support : The end support are to be given
6. Loading : Need to provide the loading pattern and the loading combination
7. Analysis : Need to Analysis the modal and all the Input Specification are Given
8. Design : Finally the Design are to be done
2:2: Explain the difference between Fixed and Enforced support condition in STAADPro
ANS :
- In STAAD, support displacement loads cannot be applied to such models when the FIXED type of support is specified.
- For the ENFORCED BUT type, there is no provision to specify a spring constant.
- The only choices, which are built into the program, are - zero stiffness
3:1.Explain the steps involved in analysis of a model using STAAD Pro sequentially.
ANS:
The steps involved in analysis of a model are
- Before Analysis the model the load pattern and the load combination are to be provided to the model
- Then go to Analysis option
- Define Command
- Select the data for the analysis of the model by perform analysis , P delta analyis ,Nonlinear analysis
- It deponds upon the support conditions
3.2. Explain the two ways in which a structural framework/model can be created in STAAD Pro software.
ANS:
The two ways to model the a structural framework is
1. Creating model by Node by Node
2. Creating model by Bay frame by
3.3. Elaborate the different support conditions in STAAD Pro.
ANS :
3.4. How will you extract the stress distribution for a staircase slab?
ANS:
- The Design of Staircase slab is done by Node placement
- The creation of plate is used in stair case
- BY using Generate mesh
- The stress distribution for the staircase slab is done by viewing colour in the slab of the design
3.5. Explain the different ways to view SFD & BMD in STAAD Pro.
ANS :
- After complation of the Design the staad pro will automatically provide the BMD & SFD
- By Entering to the Post procesing process click on ok
- By clickin the beam results Deflection command
- Reaction click the beam deflection
Practical
1. Analyze the following structural elements and validate the results
A. Simply Supported Beam
a. A Simply supported beam with two point loads symmetrically placed
b. Span L = 20m
c. Load P = 50kN each
d. Both P located at 5m from each support
B.Fixed Beam
a. Span L = 16m
b. Uniformly Distributed Load w=9kN/m
ANSWER:
AIM:
- To draw a 20m length of simply supported beam with two pint loads symmetrically placed and load p = 50 kN each,both P placed at 5m from each support.
- And a 16m lenght of fixed beam with uniformly distributed load w = 9 kN/m
Prcedure:
A. Simply Supported Beam.
- Open the staddpro software
- Define the units as per below image
- Add beams as per below image
- A graph seen in the window as per below image
- Then draw 20m length line with node
- And the concrete material with 0.23 x 0.23 thickness as per below image
- Then add the supports :- simply support to each node
- then add Load P = 50kN each
- Both P located at 5m from each support
- Then select the loads & defination
- Add load case details
- Then run analysis.
- There is no error in file see attached the below image.
- See the load case displacement
B. Fixed Beam.
- Draw the 16m length beam
- Define the the support as fixed
- Then add the concrete material with 0.23 x 0.23 thickness as per below image
- Then assign the loads
- Then run analysis.
- There is no error in file see attached the below image.
- See the load case displacement
- See the load case 2
- See the Reactions
RESULTS:
- Simply Supported Beam and Fixed Beam are drawn successfully
