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
