Week 1 Challenge

AIM:

To calculate the dead load and apply it in STAAD pro and do structural analysis.

GIVEN DATA:

• Span of the bridge is 12m
• Pier size is 2.5m
• Width of the bridge desk is 10.2m

PROCEDURE:

To calculate the self-weight of each structural element (RCC is 25kN/m3)

I consider as half section and calculate the half section self-weight and then multiple in two.

1. 900*225*25/1000000 = 5.06
2. 1370*350*25/1000000 = 11.9
3. 269*350*25/1000000 = 2.3
4. 1200*350*25/1000000 = 10.5
5. 1361*225*25/1000000 = 7.6
6. 1850*250*25/1000000 = 11.5
7. 2010*200*25/1000000 = 10

TOTAL = 58.86

58.86*2 = 117.72 kN/m

To using STAAD pro

1. Selected the geometry section and then enter node

2. Enter the beam
3. Next go the specification section to selected the custom >to click FZ,MZ,MY, MX> Add>support 2> Assign to selected nodes.
   

4.Next selected the prismatic>circle>2.5m dia>material CONCRETE>Add

5.To selected the cr2.5>assign to selected beam.

6.Next go the Loading>To create the deadload>Add>self-weight>Y>-1>Add

7.And then already to calculate the deadload and to selected the member load.

8.Next one is analysis and design section>Analysis commend>Add

9.Perform analysis>Run analysis>Go to post processing mode.

10.Envelope of load cases in selected list>ok.

11.Displacement

12.Shear Y

13.Bending moment

Result:

SF = WL/2

= 117.72*12/2

= 706.32 kN/m
