Thank you

Need to consider the shear stress

For 3000 kn only 2piles required how?

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

Thanks

Values are jus to elaborate

Will add it in future. Thank you for the suggestion

You could use the first one. It is the latest, in 1997. The other one was in 1980s.

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

These depend on the type of code and construction methods. Generally, the allowable tolerance is defined for the pile construction and then it is considered for the design. You may refer to the structuralguide.com website for more articles on this. The following like would solve most of your concerns. www.structuralguide.com/pile-foundation-construction/

Thank you

is that bearing capacity of soil ?

Great

Thanks

Noted with thanks

Thank you for the feed back, I will attend to it.

@@structuralguide Thankyou!!

It is correct in this case. When you need the moment, first need to calculate the moment per unit length that is 4x(2x1) x 2/2. Then the total moment 8x5 = 40

I think his derivation of the 40 KN.m moment would be,, 4KN/m2(5m)(2m)(1m)= 40KN.m,where; 1m is the nominal moment arm

Noted thanks

Thanks

Noted, thank you

A building can settle due to the weakness of the soil. That is inadequate bearing capacity, failure of soil due to the exceed of loads, etc. But for traffic movement, settling building could be rear. For high-rise buildings, this is unlike. Most probably, high-rise buildings are on pile foundations. Settlement of the deep foundation with the traffic movement is very unlikely.

Hi, we are not selling. This is shared as knowledge sharing.

This an application, when color changes, we know it is carbonated.

No, not available

Most of the devices do not have the facility to determine the bar diameter.

Your question is not that clear. In high-rise buildings, when it is connected with smaller buildings having a smaller number of floors we sometimes maintain temporary movement joints. Once most of the construction is completed and as per the calculation expected vertical deformations are almost over, we connect the two structures. We provide provision for concreting at a later stage in these types of occasions.

Thank you

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

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?

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.

If you know the properties of the soil and the foundation, you can do the modeling as usual. In the case of footing, it is not always required to have a model. You can do the calculation manually as it is not complicated. You may refer to the following link for further information www.structuralguide.com/design-of-pad-footing/

No, it is not recommended. We should have a beam and the most preferred arrangement is to connect the beam to the pile cap.

In this work example, the calculation of the bending moment and shear forces are not given. When you design a beam, you have to consider the weight of the slab, imposed load, weight of the beam, and any other loads on the slab such as partition walls, walls on the beam, etc.

Suggest to follow the code requirements.
