Could not analyze foundation - Design Mat footing on Pile using Staad Foundation

[trishamae]

Hi everyone,

I would like to ask some help on my project. the building has 2 mat footings of different levels and an elevator sump pit. When I try using the staad advanced foundation, my footing could not be analyzed. Kindly help me with this project. I have imported the analyzed file from staad so all my loadings are already placed.

The pile are stone columns 600mm diameter, 6meter depth.

I appreciate everyone's advise. I hope someone can help me finish this one. Thank you,

trish

I have attached here the staad foundation file. Where do I get the pile spring constant? Also the mat footing slab is also the floor slab of the basement area, we do not have enough space so there is no soil depth loading...
