Introduction:

1. Column are the vertical member in the Structure that can be of varying size in dimensions
2. The circular section of column is provided at the upper floor of the building for the better load carrying and access purpose

Procedure:

1. Create the model in the staad pro that can be a column
2. Go to properties in that Define parameter’s
3. Assign the circular shape of the column
4. The radius of the circular is given

1.2: How will you assign Unit system to a. std model file?

ANS:

1. To Assign unit system in the staad pro
2. Go to file menu and then settings
3. open the structural settings
4. Change the dimensions as the required units

1.3: What are the parameters to be specified while using “Bay Frame” option?

ANS:

1. To create the parameter of the design by Bay frame
2. By clicking on the Structural wizard option
3. Click on the frame model option
4. click on the Bay frame option
5. Enter the parameters like the length, breadth, height and the bay frame along the length, breadth and height

1.4: Name few codal standards incorporated in STAAD Pro software.

ANS:

1. In Staad pro the Codal standard are incorporated for the Steel, Concrete, Aluminum.
2. For the Steel the codal provision are IS 800, IS 800: 2007, IS 800:2007 WSD, IS 801
3. For the concrete the Codal provision are the IS 456 and IS 13920 for the Seismic Design

1.5: How will you specify the design compressive strength for a RCC section?

ANS:

1. Go to the Design option
2. Click on the define parameter
3. 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 location and the node spacing are given2.
2. Properties: Specify the Sectional properties of the section3.
3. Materials: Specify the properties of the material
4. Specifications: The pacifications are given5.
5. Support: The end support is to be given 6.
6. Loading: Need to provide the loading pattern and the loading combination7.
7. Analysis: Need to Analysis the modal and all the Input Specification are Given8.
8. Design: Finally, the Design are to be done

2.2: Explain the difference between Fixed and Enforced support condition in STAADPro

ANS:

1. In STAAD, support displacement loads cannot be applied to such models when the FIXED type of support is specified.
2. For the ENFORCED BUT type, there is no provision to specify a spring constant.
3. 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:

1. The steps involved in analysis of a model are
2. Before Analysis the model the load pattern and the load combination are to be provided to the model
3. Then go to Analysis option
4. Define Command
5. Select the data for the analysis of the model by perform analysis, P delta analysis, Nonlinear analysis
6. It depends upon the support conditions

3.2. Explain the two ways in which a structural framework/model can be created in STAAD Pro software.

ANS:

1. The two ways to model a structural framework is1.
2. Creating model by Node by Node2.
3. Creating model by Bay frame

3.3. Elaborate the different support conditions in STAAD Pro.

ANS:

• How will you extract the stress distribution for a staircase slab?

ANS:

4. The Design of Staircase slab is done by Node placement
5. 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:

1. After completion of the Design the staad pro will automatically provide the BMD & SFD
2. By Entering to the Post processing process click on ok
3. By clicking the beam results Deflection command
4. Reaction clicks the beam deflection

Practical

1. Analyze the following structural elements and validate the results. Simply Supported Beam
2. A Simply supported beam with two-point loads symmetrically placed
3. Span L = 20m
4. Load P = 50kN each
5. Both P located at 5m from each support

Fixed Beam

1. Span L = 16m
2. Uniformly Distributed Load w=9kN/m

ANSWER:

AIM:

1. To draw a 20m length of simply supported beam with two pint loads symmetrically placed and load p = 50 kN each, both Placed at 5m from each support.
2. And a 16m length of fixed beam with uniformly distributed load w = 9 kN/m

Procedure:

1. Simply Supported Beam.
2. Open the STAAD-pro software
3. Define the units as per below image
4. Add beams
5. Then draw 20m length line with node
6. And the concrete material with 0.23 x 0.23 thickness
7. Then add the supports: - simply support to each node
8. then add Load P = 50kN each
9. Both P located at 5m from each support
10. Then select the loads & definition
11. Add load case details
12. Then run analysis.

1. Fixed Beam.
2. Draw the 16m length beam
3. Define the support as fixed
4. Then add the concrete material with 0.23 x 0.23 thickness
5. Then assign the loads
6. Then run analysis.
