I have a question related to design of edge strip footing. Below is the sketch for illustration. The footing to be designed is a strip footing that is going to support a brick masonry wall on top. The literature on every footing design suggests that the resultant load should act within kern of the footing and if its outside the kern then increase the width and that's pretty much it. However in practice for edge strip footings the perpendicular strips are reinforced with negative reinforcement for preventing the overturning of the footing and as a result the uniform stresses distribution in soil is achieve and differential settlement/overturning is prevented. Here in my case, the building is erected from basement and the finish floor level is 4 ft above the NSL. The foundation of only one load bearing wall is to be erected 3 ft below NSL and in such case no perpendicular strips are available to prevent the overturning as they are erected below the basement level. What's your take on this? I believe if a footing is designed rigidly it will have the tendency of uniform stresses distribution in soil and will not cause overturning. Please provide your opinion on this as this is one common issue in design practice. Regards
