Mr.Basu,

B16.9 weling tees is a typical case, where if the requirements pertaining to crotch ridius and thickness are not met, user has to override the Caesar default values at least till version 4.3 . Second, 31.3 does not consider the effect of a reduced intersection and in order to be conservative, user can use the Schneider option in the Caesar Configure set up where if the d/D ratio is in the range 0.5 to 1, the out of plane Sif gets multiplied by a factor ranging between 1 and 2.

But Schneider's work was rather given a solid footing by Rodabaugh's work which is documented in WRC 329.Particularly for reduced intersection, the user who wants to be conservative, can use the WRC 329 option.
