Dear Safeians
I ma working on a 22 Storey Building. we have assume a Raft foundation of 5' for it.
Net bearing capacity after overburden relief is 8kip/ft2. And i am getting 10Kip/ft2 soil pressure under service loads at some locations.
one of my friend said use stress averaging to minimise the values as these soil pressures are nodal results of finite elements.
do somebody have any clue how to do that using safe .. or Excel.
