Week 10 Challenge

Aim : Calculate the snow loads

Span of the bridge is 10m .The snow is settled snow.

The deck of bridge is flat with B <30 degree.

The depth of accumulation of snow is 1250 mm.

Given that:

Span =10m

The snow = settled snow(Load=200-300 kg/m³,so max value adopted=300 kg/m³)

The deck of bridge =flat with B <30 degree(Shape co-efficient , µ = 0.8

The depth of accumulation of snow = 1250 mm.

Calculations:

Snow load, S­­­­­° = density x area

=3*1.25(Depth)*10(Span)

=37.5 Kn/m

Design snow load, S = µ x S°

= 0.8 x 37.5

Design snow load, S = 30 KN/m

Staad pro Modelling:

Creation of Origin:

Right side Nodes panel->x,y,z=0

Creation of First pier:

Right side Nodes panel->x=0,y=10,z=0

Using Add beam option Connect Node 1 and Node2

Assigning properties to Pier(Assuming 2 m dia )

Click Properties tab on Main panel->Click on Define tab on right side properties window->Circle=2m-> Add->Close

select Cir 2.0 Concrete on Properties panel-> Using Beam cursor select beam –Assign to Selected beams-> assign

Assigning Fixed support to Pier

Click Supports tab on Main panel->Click on Create tab on right side Supports window->Create-> Add

select S2 Support onSupports panel-> Using Node cursor select Pier bottom –Assign to Selected Node-> assign ->yes

Using Translational repeat method adding Rhs piers(3Nos):

Select Pier using Beam Cursor->Under geometry Tab ->Translational repeat->Global direction=Z,No. of Steps=3,Default Spacing=4m, ->Ok

Creating 10m span’s Opposite side piers

Select all Beams using Beam cursor->Under geometry Tab ->Translational repeat->Global direction=Z,No. of Steps=1,Default Spacing=10m,Check Link steps and Open Base->Ok

Assigning properties to Main Girder:

Click Properties tab on Main panel->Click on Define tab on right side properties window->Rectangle,YD=1.5,ZD=1-,Concrete-> Add->Close

select Rect 1.5 X 1.0 on Properties panel-> Using Beam cursor select beams parallel to X-axis –>Assign to Selected beams-> assign

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=10,so 10/0.5-1=19 plates required)

• Select plate cursor->select top plates ->Translational repetition ->, global direction=x->No. of steps =19->Default spacing .5->O.K.

Creation of mesh for slab in 1 –direction(Z=15,so 15/0.5-1=29 plates required)

• Select plate cursor->select top plates ->Translational repetition ->, global direction=z->No. of steps =29->Default spacing .5->O.K.

Creation of mesh for slab in -Z –direction(Z=3,so 3/0.5=6 plates required)

• Select plate cursor->select top plates ->Translational repetition ->, global direction=z->No. of steps =3->Default spacing - .5->O.K.

Assigning thickness to slab plates:

By Selection all plates ->properties->plates->Thickness 0.9->Add

Complete Render View

Assigning Loads:

Select Loading tab in the main panel->Select load case details in Loads & defination panel->ADD->In Primary window Number=1,Title=Snow Loads->Add

Select all girders:

Select tab top panel,Select Beam cursor->Beams tab -> parallel to X

Click at Newly created Snow load->Add->In the Add New:Load items->Click at member load->Select Uniform force->Add-Close

Select newly created UNI GY -30kn/m->click at Radial button of Assign to Selected beams->Assign button->Yes

Select Loading tab in the main panel->Select load case details in Loads & defination panel->ADD->In Primary window Number=2,Title=Irc min snow load>Add

Click Irc-Min Snow load->Add->Plate loads ->Entrer w1=-9kn/m2,Direction=Gy->

-Add->Close

Select All plates using Plate cursor->click at PR GY -9 KN/M2->Assign to Selected Plates->Assign->Yes

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)
