    Tank Ring beam footing

    Hi all, please advice the method to go about designing a annular raft for a tank ring beam. Could the choice be to design the strip footing/raft as per the method used is design footing for walls or I need to determine radial and circumferential moments.

    Soil Stresses

    Sorry I was referring to ASCE 7-10. General foundation design and checking of soil stress under the foundation.

    Seismic bearing capacity soil check

    Hi guys, Please how do u check for seismic bearing capacity of soil response under a raft. Is it advisable to use load combination 5 and 7? Do I need to define it a liner load cases or nonlinear load cases. Thank you.

    Soil Stresses

    thread507-276770 Please, can you again use load combination 5 and 7 to determine the seismic bearing capacity soil under the footing? Do u have to define the load case as a nonlinear load cases? Or perhaps there are other methods. Regards.

    how to model Soil Structure Interaction on Etabs,Sap2000

    Hello fellow engineers, I think there is no one way in modelling soil stiffness as links or area Springs. Most handbooks I have read about soil structure interactions with raft foundations always uses area Springs. Let me share my method even though I have not concluded it's the best way. I...

    Footing Stresses

    Hello all, Please, how can we determine the bearing stress of a footing in etabs and comparing it with allowable bearing pressure. Does anyone has this experience in ETABS?

    Uplift in raft foundation

    thread802-200891, please how do you determine if there is an uplift in a raft foundation?

    Etabs area spring

    Can you share your non linear load cases? Did u model the soil structure interactions in etabs, how do you identify when there is an uplift?. @avecillasjavier, please what value should be used for the restraint in the X and Y direction. What I did was to select the nodes of the raft and assign...

    Etabs area spring

    Hello mates, Please i want to perform a soil structure interaction in etabs 2013. I have assigned area spring of 60000KN/M2/M, in the 3 direction, is my definition correct. I was confused if the modulus of subgrade needs to be negative. I also want to know how to place a restraints in the x...
