Week 2 Challenge

1.

• assign Circular section to column:

GO to properties >> Define section >> Circle

• assign Unit system to a .std model file :

Open std. software >> choose Units system >> English/metric

• the parameters to be specified while using the “Bay Frame” option:

>> Length

>> Height

>> width

>>No. of bays along the length

>> No. of bays along the width

>> No. of bays along the Height

• Name a few codal standards incorporated in STAAD Pro software:

>> IS 456:2000

>> IS 800: 2007

>> IS 13920:2016

• specify the design compressive strength for an RCC section:

Go to design >> Define design parameters >> specify Fc value.

2.

• State the “Input” steps involved in RCC design.

<> first create an analytical model of the structure

<> input properties of the structure

<> input properties of structure

<> input supports and specification

<> input load and load combination

<> input design standard

<> specify analysis type

<> run analysis

<> verify the result

<> Design of RCC

• Explain the difference between Fixed and Enforced support conditions in STAADPro.

Fixed support conditions	Enforced support conditions
there is no settlement value input in it.	There is settlement value input in it.

• Explain the steps involved in the analysis of a model using STAAD Pro sequentially.

<> Read the drawing provided

<> first create an analytical model of the structure

<> input properties of the structure

<> input properties of the structure

<> input supports and specification

<> input load and load combination

<> input design standard

<> specify analysis type

<> run analysis

<> verify the result

<> Design of RCC

<> Represent the design as a document and drawing.

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

<> By using nodes and beams

<> By using a structural wizard

• Elaborate on the different support conditions in STAAD Pro'

<> Fixed: The degrees of freedom are fully restrained.

<> Fixed But: The degrees of freedom are not fully restrained.one of the degrees of freedom is assigned as a spring.

<> Pinned: only the translational moments are restricted and the other three moments are free.

<>Enforced: The degrees of freedom are fully restrained but support displacement is also assigned.

<>Enforced but: User can select which degree of freedom wants to restrain and how much support displacement is assigned.

• extract the stress distribution for a staircase slab:

<> After designing the staircase

<> Go to post-processing >> plate result >> max absolute stress

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

<> using force method

<> using graph

PRACTICAL

(1)

AIM: Analyze the following structural elements and validate the results

Specification:

a. A beam of span 20m
b. Support: Simply supported
c. A point load of 50 kN at the 5 m away from both support
d. Draw SFD and BMD using software

Procedure:

• First, create a file in STAAD PRO.
• Now create two nodes with a distance of 20 m between them.
• Add beam
• now define a property of the beam.
• Now create two support-pinned

• Now assign the pinned supports to end of the beam.

• Now define the case and put the value 50 KN and assign it to the beam at 5 m and 15 m from the one end of the beam.

RESULT:

• SFD of Beam

• BMD of beam

AIM: Analyze the following structural elements and validate the results

Specification:

a. A beam of span 16m
b. Support: FIXED supported
c. A distributed load of 9 kN/m
d. Draw SFD and BMD using software

Procedure:

• First, create a file in STAAD PRO.
• Now create two nodes with a distance of 16 m between them.
• Add beam
• now define a property of the beam.
• Now create two support-pinned

• Now assign the fixed supports to the end of the beam.

• Now define the case and put the value 9 KN and assign it to the beam

RESULT:

• SFD of Beam

• BMD of beam
