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 dimentions 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, Concrete, 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 loadina 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.

• 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 clicking 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
