AIM:-

1. 1. How will you assign Circular section to column?

Procuder:-

Answar:-

First Go toi the Properties
Than Selct the Define
Open this Diloge box Properties
And Give the Radius of the member
Now Create the Circular Column

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

Answar:-

First Go toi the View
Than Selct the Option Display
Open this Diloge box options
Than Selct the Structural Units

3. What are the parameters to be specified while using “Bay Frame” option?

Answar:-

Go to geometry tab in that select structural wizard
that select frame model in that select bay frame
Give the parameters like length, height, width,
No. of bays along length, No. of bays along height and No.
of bays along width

4. Name few codal standards incorporated in STAAD Pro software.

Answar:-

Euro code, ACI, IS code

5. How will you specify the design compressive strength for a RCC section?

Answar:-

In design select materials as concrete
select the code and then go to define
parameters and select FC then specify the value

2) 1. State the “Input” steps involved in RCC design.

Answar:-

Steps involved in RCC design are
Geometry
Properties
Materials
Specification
Support
Loading and Load combinations
Analysis
Design

2. Explain the difference between Fixed and Enforced support condition in STAADPro.

Answar:-

When the fixed type of support is specified, for those degrees of freedom which are to be treated as fully restrained, STAAD
assumes the displacements to be known quantities whose value is zero. Hence, these degrees of freedom are not considered
for the stiffness matrix and their value is not calculated
When the enforced type of support is specified, for those degrees of freedom which are to be treated as restrained, STAAD
assign a spring with a spring stiffness – translational stiff springs for translational restraints and rotational stiff springs for
rotational restraints. Those degrees of freedom which are free to displace are assigned springs of zero stiffness. Hence for all
the 6 degrees of freedom at such supports, the displacements are calculated. The one which have a stiff spring with end up
having a negligible displacement and those with zero stiffness springs will have a displacement based on the structure
geometry, properties and loading

3) 1. Explain the steps involved in analysis of a model using STAAD Pro sequentially.

Answar:-

Read or study drawings (Plan/Elevation/Section)
Input Geometry
Input Properties
Input Specifications/Constants/Supports
Run analysis
Specify analysis type
Input design standards
Input load and load combinations
Verify results
Design
Represent design as document and drawing

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

Answar:-

Node by node method
Grid method
Structural wizard method

3. Elaborate the different support conditions in STAAD Pro.

Answar:-

Fixed support
Pinned support
Fixed but support
Enforced support
Enforced but support
Multilinear spring support
Foundation support
Inclined support
Tension/Compression Only Springs support

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

Answar:-

Create the staircase by using the nodes in the geometry panel
After creating the nodes assign the plate elements as the slab property after that define load cases and calculate the area load
acting on the staircase and apply load cases and load combination to the staircase slab and then create a mesh on the plate element
After that run the analysis and go to post processing mode and click on plate result option in that select stress distribution
result and choose the stress type accordingly and that stress distribution result is displayed
Maximum and minimum stress values are displaced

5. Explain the different ways to view SFD & BMD in STAAD Pro

Answar:-

After completing the design and running the analysis software will provide the BMD and SFD

After the analysis click on Post processing mode and click OK

Go to deflection command and click on beam result

In reaction command 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

Answar:-
