How to reduce stress concentration

Would it be possible to replace the fixed support with a spring support?
In cases where the boundary conditions are unclear, such as additional displacements at the pipe ends, it is difficult to determine whether the supports are appropriate. However, purely from the perspective of software accuracy, one could try placing a gap at this fixed point, or take the actual stiffness of this fixed point into consideration.
Do not use software indiscriminately; each software has its appropriate scope of use
There seems to be an issue with the mounting bracket here; if what’s nearby is a pipe outlet, installing a bracket in this location will result in excessive stress on the pipe outlet. Therefore, the design of the bracket needs to be modified.
Careful consideration is needed when setting fixed supports, and the piping structure can also be modified
Do not use non-professional pipeline stress software to calculate pipeline stress problems casually.
