I am trying to investigate whether the exisiting pile cap with 13 pile beneath them is capable of taking an increased load or not. I am considering modelling the pile cap in Staad Pro as solid elements. how do I define the supports?. Existing piles were designed to take compression only and no...
Jike, Thanks for your views.
Well, here's what I did. The portion of the foundation on existing foundation is anchored. The peripherial portion of the new fdn is connected to the existing fdn by driving anchor bars. So, I defined those support points as fixed in my model and all the other...
Two pairs of couple forces act on the foundation. Existing is a spread footing on pile foundation. I need to control the settlement. Hence using Finite element. The loads are from a pipe support structure. Thanks.
I am designing a foundation of size 16'X 11'.Depth is 2' for the left 6' and 4' for the remaining length of the foundation. It rests partly on a existing foundation (2'ft depth portion) and rest of the length(with depth 4') is on soil. I will use modulus of subgrade of soil for the soil portion...
JedClampett, Thanks for you reply.
Well, the foundation is for a pipe support. There are 4 points of loading on it. The main load is a 56 kips couple at 2 pairs of supports. These 4 points rest on the foundation. There is an existing foundation close by and part of the new foundation requires to...
I am designing a foundation which rests partly on soil and partly on a existing concrete foundation. I am modelling it in Staad pro. I know the modulus of subgrade for soil. My question, how should I model the portion of foundation slab on the existing foundation? What are the constants that I...
