Week 2 Challenge

AIM :  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 
• 

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 

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 

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 

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 Fck 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 

    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    

1. 

    3. Elaborate the different support conditions in STAAD Pro.

ANS : 

    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 

    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

ANS :
