Week 1 Challenge

AIM : TO Calculate the Dead Load and apply it the Staad PRO and analysis the structure

INTRODUCTION : The Project of Box Girder Bridge for Bay of Bengal ,Whose data is give below-:

Width of the Bridge Deck 10.2 m

Span of the Bridge is 12m

Pier size is 2.5m Diameter

Wind Speed is 47km/hr

Procedure in detail:

Self Weight of deck slab =width *Thickness*unit weight

10.2*.225*25

=57.375kN/m

Self Weight of Box Girder =width *Thickess*unit weight

2.083959*25

=52.09875kN/m

Total weight of Box Girder Bridge =57.375+52.09875

=109.47375kN/m

THEN , steps how can generate in the model

Frist node to assign then add the beam .

Step2 : then useing the translational repeat command and add beam

Step3 : then add the plate

Step4 : then Select the nodes and assign the supports

Step5 : then turn by turn select the geometry and assign the Properties

STEP6: then apply and assign the SELFWEIGHT on structural element

Step7: then apply and assign the dead load on structural element

Step8: then save the file and assign run analysis

Step 9 : then Check the Deflection ,Displacement and all deformation on the structural element

RESULT : Total dead load act on the bridge is 109.47kN/m
