Week 2 Challenge

1. 1. How will you assign Circular

section to column?

 

ans-

go to properties 

assign circular shape of column 

next close 

RESULT -

CIRCULAR SECTION OF column is assign .

 

 

 

 

    2. How will you assign Unit 

system to a .std model file?

 

GO to menu > Settings 

-open structural seetings 

-change in here dimesions 

 

    3. What are the parameters to be

specified while using “Bay Frame” option?

 

-by clicking structural wizard option 

-click frame model and the way frame 

-enter parameter like length ,bredth 

height ,and  bay frame along length ,

width , and height .

 

 

    4. Name few codal standards incorporated

in STAAD Pro software.

 

IS  456 : 2000

IS 13920-2016

IS 875 -1987 

IS 800 -2007 

IS 1893 -2016

    5. How will you specify the design

compressive strength for a RCC section?

 

GO to design option > click define parameter 

click Fc . give value - 25000 KNM.

 

 

 

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

ans-

1.GEOMETRY -

Give node location  and spacing 

 

2.properties -

give  properties in here 

 

3.MATERIAL 

PROVIDED SPECIFIED MATERIAL AS LIKE CONCERETE .

4. SPECIFICATION .

5.SUPPORT PROVIDED 

6.PROVIDED LOADING PATTERN OR LOADING COMBINATION .

7.ANALYSIS AND

8.DESIGN 

    2. Explain the difference between Fixed

and Enforced support condition in STAADPro.

 

 FIXED SUPPORT IN HERE DEGREES OF 

FREEDOM IS FULLY RESTRAINED 

 

-ENFORCED CONDITION - degree of 

freeedom is free to displace , in 

here ends of support free to allow 

to move or rotate.

hense all  6  ldegree of freedom 

moments are calculated in here .

 

 

 3. 1. Explain the steps involved in

analysis of a model using STAAD Pro sequentially.

 

ans-

-creat model and add nodes and creat by 

structure wizard option .

-add beams .

-choose properties .

-add supports 

-add specification   ,  loadings  ,

-apply perform analysis 

-run model 

-go to post processing 

-take displacement , BMD , SHEAR  forces .

 

 

 

    2. Explain the two ways in which a

structural framework/model can be

created in STAAD Pro software.

 

ans-

1.ANALYTICAL MODEL 

2. PHYSICAL MODEL 

 

physical modeler takes advantage of

physical modelling  a structure , which

give more accurate modelling results .

beams and surface are placed in model

on scale of which they would appear

in physical world 

    3. Elaborate the different support conditions in STAAD Pro.

-FIXED SUPPORT -

translational and rotational displacement 

are restrained .

 

-PINNED 

traslational displacement are 

restrained but rotation are not restrained 

 

FIXED BUT -

fixed but similar to pin support 

it allows to degree of freedom to view the

displacement either translational or rotational .

 

ENFORCEMENT BUT -

SOFTware assign the springs it self

zero stiffness or high stiffness 

 

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

-after analysis go to post processing

-select load combination 

-click on plate result 

-select plate stress contours 

-select load combination 

-check  max. absoulate stress 

-check major principle stress 

-check MX [local]

-

 

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

 

 -run and analysis complete 

-than goto postprocessing 

-click  moment and sfd tool at to 

of menu bar shown SFD AND 

BMD RESULTS .

-GO TO  GRAPHS  AND check view sfd and 

bmd diagrams 

-double click for member 

 

 

 

 

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
