As far a transfer beam/slab is concerened we need to remember that it is providing an elastic support to the column from above levels. The beam/slab is under stress and hence deflecting due to the loads from the column. Due to this deflecting behavior there are high stresses at the corners (also can be related to the punching effect). I did a transfer slab, with the same problems of high stresses, did provided sufficient reinforcement and stiffness to counteract the same.
Also I would like to echo the comment made by Zippaton, that instead of using a point load analyse the transfer beam/slab for a line load, which will infact be the actual condition, the results will be quite different.
The high stresses need to be addressed as suggested by allagui10. If allagui10 can provide us with a sketch as to how the stiffners can be provided and the junction detailed.
I have my doubts regarding taking the average of the stresses.
Jaks.
