How to Design the Pile Cap for 2 piles

[@aneeshaunni1554]

Can you share the details of the bar arrangement according to the pile cap dimension?... lik e bottom first u bar in longer dimension or shorter?

[@structuralguide]

We can have the critical bar at the bottom layer. That can be done. Since we tie the rebar, and is within the concrete, the necessary restrain is there for tension bars. You may also detail like a beam manner that distribution bare acts like a link too. In that case, reduction of the effective depth shall be considered in the design.

@@structuralguide thank you somuch

[@binayaksamanta863]

Please make a video on 3 pile design

[@structuralguide]

Will do it soon

Sir , how the Vc value 0.75 found out from table 3.8 bs 8110 using this v value?

[@structuralguide]

Vc is obtained based on the 100As/bd and effective depth.

[@rashminsajeev2893]

Sir, In our case, 100 As /bd = .72 and eff. Depth is > 400 . Couldnt find a value 0.75 (Vc) corresponfing to these data frm table 3.8?

[@structuralguide]

Now it is clear what you are asking. The Vc that I have considered in the example is some approximation. The correct value needs to be obtained form the table based on the 100As/bd and as per effective depth.

How to decide pile nos

[@sudeepta2869]

For 3000 kn only 2piles required how?

[@structuralguide]

@@sudeepta2869 The Number of piles required depends on the pile capacity (structural and geotechnical)

Can u pls make 10:45 clear

[@structuralguide]

We have to maintain the spacing of the pile to design the pile cap with the truss method. When the spacing of the piles is more, we have to use the bending theory; calculate the bending and shear and design like a beam.

[@fathimathangal1913]

At 14:52 how is the area just the effective depth, pls male that clear

[@structuralguide]

Area, here means the b x d b - width d - effective depth
