Abstract:For solving the inconsistence problem among existing theoretical
   solutions of the critical temperature for cylindrical thin-shell, in
   this paper, the theoretical solution of critical temperature was firstly
   deduced for a cylindrical thin-shell subjected to a uniform temperature
   rise based on Donnell equation. And then the numerical solutions of the
   flat-plate and the cylindrical shell were constructed separately.
   Lastly, comparison analysis between the theoretical solution and
   numerical solution was carried out, and the exact solution was obtained
   by introducing a modified coefficient. The study work will benefit to
   scientifically design related thin-shell structures in the future.
