Week 7 Challenge

Flood Level = 2 Mtr.

Bridge Span = 45 Mtr

The Mean Volocity of the river is 3 m/s

Sol:

Flood Level = 2 Mtr

Max. Velocity = v=2 * Vmean

=2*2*2 2.828

Water Current (P)= 52*k*v2

k= Pier Shap

v2 = Maximum Velocity

= 52*0.66*2.828=274.477

Open Staad Pro .

& Drow the Sketch

Span is 45 Mtr

& Pier Height is 6 mtr.

go to loading Option

& Add Water Current Load

go to trapezoidal Option & Enter water current Pressure

& Save File

go to run Analysis

& Difflection

Attach the Staad Pro File .
