Pile - Raft Load Sharing Ratio

Pile - Raft Load Sharing Ratio

Pile - Raft Load Sharing Ratio

I am conducting some research on piled raft load sharing ratio between piles and rafts. Do you have any idea if there is an easy way to get the loads carried by piles and loads carried by soil???

I am using embedded pile to model the piles with hardening soil.

RE: Pile - Raft Load Sharing Ratio

H. Poulos and B. Fellenius, among others, have written extensively on this topic.
For a conventional pile cap over pile (doweled connection), Fellenius would say there is no bearing pressure on the bottom of the pile cap, except near pile failure.
Poulos has written theoretical work, as well as case studies on disconnected piles below mat foundations.

RE: Pile - Raft Load Sharing Ratio

I am sorry, I didn't write Plaxis. I have read these resources, my MS topic, but I want to see this on Plaxis 2D 2015.

RE: Pile - Raft Load Sharing Ratio

The load sharing depends on many factors. Some of the factors includes : the number, size and location of the piles, the rigidity of the slab, the soil profile and loading.conditions.

RE: Pile - Raft Load Sharing Ratio

Sum the pile reactions and what load remains is taken by the cap/soil interaction.

White Paper - Design for Additive Manufacturing
With a growing number of parts manufactured directly by additive manufacturing techniques, it is important to lay down design principles suitable for such manufacturing processes and to ensure parts are designed for additive manufacturing. There are several factors that are to be considered at the design stage. Few such design issues in additive manufacturing are discussed in this paper. Download Now
