Week 8 Challenge

Aim: To calculate centrifugal loads as per given data and analyse the given bridge in Staad Pro Introduction : The given bridge is of Composite steel girder bridge. It has 4 girders, The span of the bridge is 12 m. Width of carriage way is 7 m. The bridge is subjected to a live load of Class 70R tracked…

Given Data:

NO of Girders: 4

Span of the Bridge 12m

Carriage way width 7m

Live load Class 70R

Design speed 75km/hr

Radius of Curve 3m

As per Irc -6 ,

Centrifugal Force, C=WV² /127R

W=70T(700 Kn)

V=75km/hr

R=3m

C=10334.65 KN

Applying in Staad Pro:

Creating First node :

Geometry Nodes grid window->x=0,y=0,z=0

Creating First pier :

Geometry Nodes grid window->x=0,y=10,z=0

Using Add beam option Connect Node1 and Node2

Using Translational repeat method adding Rhs pier:

Under geometry Tab ->Translational repeat->Global direction=x,No. of Steps=1,Default Spacing=7m,Check Link steps and Open Base->Ok

Creating 12m span’s Opposite side piers

Under geometry Tab ->Translational repeat->Global direction=Z,No. of Steps=1,Default Spacing=12m,Check Link steps and Open Base->Ok

Creation of girder beams using Translational repeat method:

Under geometry Tab ->Translational repeat->Global direction=x,No. of Steps=2,Default Spacing=2.33m,->Ok

Creating fixed supports:

Under Supports tab->Supports Window->Create support tab->Fixed Add

Assigning Fixed supports:

Select S2 Support->Select all Pier bottom Nodes->Assign To Selected Nodes->Assign

Creation of 1.5m dia piers :

Properties tab ->Define ->Circle -> yd=1.5 -> Add -> close

Select all piers using Beam cursor->Select all piers ->Assign to selected beams ->Assign

Assigning I Girder properties:

Click on properties->Define->Tappered I-

Enter I-girder detaisl(assumed) as follows

Then click on add button

Assigning properties to the I-girder:

Click on Tapper->Select all beams Excluding Piers->Assign to selected Beams->Assign->yes

Creation of Deck slab plates:

Creation of first Plate:

• By selecting Node cursor Click on Top left corner node->geometry->Using translational repeat method , global direction=X->No. of steps 1->Default spacing .5->O.K.
• Creation of Nodes in Z-direction: Selecting top left corner nodes->Using translational repeat method , global direction=z->No. of steps 1->Default spacing .5->O.K.

Add plate->Select all four nodes one by one –O.k

Creation of mesh for slab in x –direction(x=7,so 7/0.5-1=13 plates required):

• Select plate cursor->select top left plate->Translational repetition ->, global direction=x->No. of steps =13->Default spacing .5->O.K.

Creation of mesh for slab in Z –direction(z=12,so 12/0.5-1=23 plates required)

• Select plate cursor->select top plates ->Translational repetition ->, global direction=z->No. of steps =23->Default spacing .5->O.K.

Assigning thickness to slab plates:

By Selection all plates ->properties->plates->Thickness 0.25->Add

Applying Loads:

1. Vehicle definition
2. Load case details

Vehicle definition: Loading(Tab)->Vehicle definations->Add->width 2.06-Load -10334->Distance 4.57

No of loads to be generated:(Span+vehicle )/.5 +1=(12+4.57)/.5+1=34

Load Case Details:

Under Load case details->Add->Type”Centrifugal force”->Add ->Close

Under Load case details->Load Generation-No of Load to be generated=34 Add->Close

Load & definition tab->36-39:Generate load->x=1.5,y=10,Z=0-,Z increment=0.5-> add -> Close

In Analytical Model’s Main window ,right click ->Command file editor->Type “PERFORM ANALYSIS” at the end of file Before finish.

Run analysis(Ctrl+F5)

Displaying results:
