The support stiffness values which are in-built in the calculations of COADE program are 10e6 kg/mm or so . Has this value been arrived at based on some experiments or logic ? Obviously the value has to be high enough to represent a real rigid support. But is there any specific logic for the value ? Is it that the same value is used by other softwares equivalent to CAESARII like Autopipe , CAEPIPE etc. ?
