  1. Plz explore these questions. Q1:How to define bearing capacity of soil in SAFE? Q2:what is mean by the different terms used in SAFE Detailing drawing like TC,BF,BE,BC etc i think T for top and B for Bottom but the others? Q3:In SAFE as shown in figure what does the negative shows,if it shows direction then why it is given Max name to minimum value and Min name to maximum value for deflection as (Max=-0.068269in and Min=-0.118905in)? Q4:What is mean by Subgrade Modulus in SAFE and how we will calculate its value? Q5:For Five storey building my mat foundation possesess Punching shear values as shown so,what to do with sides although the thickness of mat is 48"? Q6:I need mat foundation reinforcement drawing please.

  2. For Defining Modulus of Subgrade in SAFE see the 1st pic in attachment As in the figure you uploaded for punching shear results it is clear that u are getting values of the ratio more than 1 which is not oK ..As far as the 5' thickness u have specified for this Raft is too much ..Kindly check the Loadings in ETABs

  3. in Safe , you have to provide value of modulus of subgrade, you can't define bearing capacity. Geo technical report should mention actual modulus of subgrade , otherwise you have to do it on the basis of load and allowable settlement. ( BOWLES - Foundation Analysis and design) As you have mentioned that you are new in this field, you should concentrate on manual calculations, it would be utter madness if you simply accepted your software results without any manual checks and without any involvement of your engineering. if you are giving 48 inches raft for 5 storey building, it is too too much ( if it is commercial or residential), it means your loading ( live and dead loads) need correction. verify them from UBC OR ASCE. Calculate Punching manually first.

    Aslam Kassimali's book can also be consulted. You can find it on this link: https://skydrive.live.com/redir?resid=35DD3B5349D6D025!3299&authkey=!ACpYP6NJabY6gHw&ithint=file%2c.pdf
