I have a doubt in the reaction tab in post processing of staad. In Static check results, its shows three rows namely as loads, reactions and difference. In which difference is almost or is equal to zero. But for a particular load case, summation of all moments available in Support reaction window is not equals to the moment available in the Static Check results.
My question are
- Why there is a difference between both cases?
- for foundation/pedestal design which reaction we should take (for combined footing)?
Thanks in advance for any replies.
