Week 2 Challenge

1.1

Answer:

To assign circular sessions to columns the following procedure has to be done

• Crete the model in Staad pro
• Select the Define parameter and select the properties
• Now assign the circular shape and radius of the column

1.2

Answer :

To assign Unit system to a .std model file, the following procedure has to be followed:

• Go to the File menu and select Setting
• Now go to the structural setting and change the parameter as required

1.3

Answer:

The parameters to be specified while using “Bay Frame” option are length, height , width and the number of bays along length, height and width.

1.4

Answer:

Few codal standards incorporated in STAAD Pro software are :

• For Steel :- IS 800, IS 800:2007, IS 800:2007 WSD, IS 801
• For Concrete :- IS 456
• For seismic design :- IS 13920

1.5

Answer:

To specify the design compressive strength for a RCC section, the following steps has to be followed:-

• Go to the Design menu, and click on the Define parameter
• Now in the design paramter the compressive strength will be already mentioned, which can be changed

2.1

Answer:

The “Input” steps involved in RCC design are:-

• First of all, the imported step Geometry, in which we assign the node location and node spacing.
• Next we have to specify the Properties of the section
• Then we have to specify the Material
• Then the Specification
• Then, the Support
• After the Support, we have to provide the Load pattern and the Load combination
• Now we have to do the analysis and finally the design has to be done.

2.2

Answer:

The difference between Fixed and Enforced support condition in STAAD Pro is that, the support displacement loads cannot be applied to those models which has Fixed support condition: But for Enforced support condition, there is no provision to specify a spring constant value, it is already in the software.

3.1

Answer:

The steps involved in analysis of a model using STAAD Pro sequentially are as following:-

• Assign the Load pattern and load combination to the model
• Now go to Analysis Option and define command
• Now select the data for analysis (which depends on the support condition) by perform analysis, P delta analysis, Non-linear analysis.

3.2

Answer:

The two ways in which a structural framework/model can be created in STAAD Pro software are :-

• Creating model by Node by Node
• Creating model by Bay frame

3.3

Answer:

The different support conditions in STAAD Pro are:-

• Fx
• Fy
• Fz
• Mx
• My
• Mz

3.4

Answer:

To extract the stress distribution for a staircase slab, the following are done:

• Using the node placement, we can design the staircase slab and the plates used in stair case
• Now by using the Green mesh, we can check the stress distribution for the staircase slab

3.5

Answer:

The different ways to view SFD & BMD in STAAD Pro. are:-

• The STAAD will automatically provide the SFD and BMD after the Design
• By entering to post processing process,
• By checking the Results
• By clicking the Beam result deflection

Practicals

1.A

Aim: To draw and analyse a Simply supported beam with given data

Procedure:

• Open STAAD Pro software and define the units
• 
• Now we have to add the beams and now the graph will be seen in the window
• 
• Now we have draw a 20m length line with node and assign the material concrete 0.23*0.23
• 
• Now we have to provide the supports at the ends , which is the simply supported
• 
• Now we have to add load(P=50 KN ) and we want to locate point P, which is 5m from each support
• 
• Now we have select the load definition and we need to add the load cases
• And then we have to do the Run analysis and check if there is any error in file.
• Now we have to check the Load Case displacement
• 

1.B

Aim: To draw and analyse a Fixed beam with given data

Procedure:

• Open STAAD Pro software and define the units
• 
• Now we have to add the beams and now the graph will be seen in the window
• 
• Now we have draw a 16 m length line with node and assign the material concrete 0.23*0.23
• 
• Now we have to provide the supports at the ends , which is the fixed support
• Now we have to add lthe uniformly distributed load (W=9KN/m)
• 
• Now we have select the load definition and we need to add the load cases
• And then we have to do the Run analysis and check if there is any error in file.
• Now we have to check the Load Case displacements
• And we can see the reactions as well
