Respected Engineers!
what is the purpose of providing strap beam over combined footing? (someone told me that in this way we can decrease the amount of top steel on combined footing)
how i can design it using safe? either have to assign a beam property or strap having thickness combine footing + strap beam.
should strap beam merge with the isolated footing to be the strap footing together? Or, can I cast the strap beam above the isolated footing so that there is a gap between isolated footing and the strap beam?
