How to import multilevel raft foundation from etabs to safe.
main designer has designed it as a raft foundation with a bearing capacity of 150 kn/m2 but after the site development and excavation we found a hard strata that can with stand with 250 kn/m2(as per the soil report). as total depth of raft is 1 m that is too much for 5 storey car parking, i want to modify it with 250 raft overall with inverted panels under column. but i am not able to import that multi level foundation reactions as a one file in Safe. because in etabs u can only export one storey .
please give your helpful suggestions.
