Challenge 4
Prepare a longitudinal model of I-girder and analyse for all the loads with following specifications:
- Grillage model of 4 I-girders with span length of 27.0m.
- Having supports at 0.700m from both ends.
- Having following geometrical properties:
End Section: Area = 1.218m2
Iy = 0.32541m4
Iz = 0.05129m4
Mid Section: Area = 0.87702m2
Iy = 0.27835m4
Iz = 0.02622m4
4. Having material properties: Concrete, M60 grade
AIM OF I GIRDER
Girder bridge are the simplest bridge type in structure and consist of steel beams shaped to an I section
girder bridge are comprised of deck slabs on which vechicle and people pass and main girder supporting the deck.
This girder is almost used in the large construction of structures.
ANS- I am submitting the whole solution by screenshot whatever challenges is given in it .

ANS- I am submitting the whole solution by screenshot whatever challenges is given in it .
STEP 1 - CREATE THE LONGITUDINAL AND TARVERSE LINE BY PUT THE NODE VALE
IN FIG MENTION THE ALL NODE VALE .
-
STEP 2- GO TO SUPPORT AND CREATE THE SUPPORT OF BEAM STRUCTRURE
STEP 3 SUPPORT PROVIDE THE ROLLER SUPPORT TO BEAM SELECT THE BEAM ALL AND ASSIGN TO SELECTED BEAM
STEP 4 GO TO THE PROPERTY
STEP 5 THEN GO DEFINE AND GO GENERAL FOR PUT THE MOMENT LOAD OF COORDINATE
STEP 6 THEN PUT ALL VALUE Ax Ix Iy Iz
1.75808 0.1818 0.6802 0.285
1.41702 0.07 0.625 0.26
1.59 0.126 0.652 0.272
STEP 7 GO DEFINE AND CLICK ON RECTANGLE AND CREATE THE THICKNESS OF BEAM DUMMY
STEP 8 CREATE ALL SECTION BEAM WITH MATERIAL
STEP- 9 CLICK ON LOADING AND GO TO VECHICLE DEFINITION AND PUT THE LOAD AND DIST
STEP 10 GO TO LOAD CASE DETAILE
STEP 11 IN DEAD LOAD FOR SELFWEIGHT PUT -1 IN GOLOBAL Y DIRECTION
STEP 12 GO TO SIDL LOAD AND CLICK ADD THEN GO TO MEMEBER LOAD AND CLICK UNIFORM
FOR FIND DIRECTION OF LOAD IN GOLOBAL DIRECTION DEAD LOAD SIDL LOAD ETC.
STEP 13 APPLIED ALL LOAD ON BEAM LIKE SIDL DEAD LOAD .
STEP 14 AFTER LOAD APPLIED THIS ISOMETRIC VIEW I GIRDER
STEP 15 LOAD APPLIED UNIFORM -23.5 OF I GIRDER THIS VIEW
STEP 16 LOAD APPLIED ON I GIRDER VERTICAL OF THIS VIEW
STEP 17 GO TO LOADING AND CLICK LOAD GENERATION AND PUT THE LOAD VALUE AFTER FIND THE METRO VIADUCT
STEP 18 GO ANALYSIS AND DESIGN AND CLICK ON RUN ANALYSIS
STEP 19 THEN GO TO POSTPROCESSING AND CLICK ON APPLY THEN CLICK OK FOR CHEAK LOAD
STEP 20 AFTER THIS VIEW IN THIS WE KNOW MAXIMAM AND MINIMUM LOAD WHERE
STEP 21 IN THIS VIEW AFTER ALL LOAD APPLIED WE THE BENDING MOMENT OF THIS STRUCTURE
STEP 22 GO TO SUMMARY AND CLICK SELECT LOAD AND THEN GO TO LOAD GENERATION AND CHEAK WHERE
SIDL AND DEAD LOAD MAXIMUM AND MINIMUM
STEP23 CHEAK MAXIMUM AND MINIMUM LOAD APPLIED WHICH NUMBER OF BEAM CHEAK
I write some about m60 grade concrete
In 4t amendement of IS 456-2000, m60 grade has shifted
it is standard concrete M25-M60
this is used in .
- M60 grade of concrete is used in reinforced cement concrete (RCC) construction where high compressive strength is needed like high rise buildings, bridges having long distance etc.
- It is used in critical environment construction.
- M60 grade of concrete is used in Spillways of dams.
- In m60 grade concrete traget strength= 60mpa maximum size of aggregate used 12mm and specfic gravity of cement 3.15
and specfic gravity of fine aggregate =2.6
