What the best Foundation system for this building. Please choose between the 3 options
Salam Alaykum, The building is low rise, 4 floors building and consists of 10 Joints. each koint has 14m Width, about 40m Length and 4 floor height. Model in Etabs had been made for one typical joint with wind and searthquake design. Export to Safe had been done. What is the best Foundation system to be used: A- Raft footing under each joint.(so we will have 10 raft footings with 2cm expansion joint between the rafts) this will give high pressure on the perimeter columns B- One Raft footing under the building. so we will have one raft footing with 14m width and 400 m length. the expansion joints will be for the superstructure only and will **t be in the sub-structure. C- Isolated footings will be used under under each columns with top and bottom reinforcement. As my k**wledge, this is should **t be used since the building should be supported by raft footing in order to resist the lateral load (raft and wind) **te that in all the 3 cases, the soil pressure is less than the allowable soil pressure. Please advise. Salam .
