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
