In Manual design Era :
We used to analyse frames using Kani's Method,,
The stiffnesses (I/L ) were taken as under:-

FRAME BEAMS MONOLITHIC TO COLUMNS :-
FOR T BEAMS - 2.0 I/L
FOR L BEAMS ...

Modulus of subgrade reaction is =( Load/area )/ settlement.

Bowels formula K = 40*SBC*FOS

The formula considers 25mm settlement of foundation

At ultimate Bearing capacity , settlement of 2 ...
