A foundation is to be constructed for a small residential building that is approximately 6.0 metres wide by 8.0 metres long. The foundation will consist of a strip footing that is 0.6 metres wide, along the bottom of the foundation wall, and 2 pad footing for central columns with dimensions of 1.2 metres by 1.2 metres. The total weight of the structure is estimated to be 2550 kilonewtons. What is the bearing pressure of the building, in kPa?
pls replyy asap!!
Question:- 1. If the foundation system is given a vertical load of 400 kN and a moment of 40 kN m. calculate the safety factor for the foundation system. (Hint: calculate load distribution at the base of the foundation) and If the required design criteria is SF 3.0, does the foundation system still meet the requirements? If not, what is your suggestion to meet the design criteria?
