This roof system is used in structures which have large spans and require light roof loads. Commonly it is a cast-in-place concrete, although it can be precast panels. The shell is normally thinner than a typical concrete roof system. The most common type is a cylindrical shell adapted for rectangular planned structures. The shell is thicker near the supports due to the bending stresses. Based on individual designs, there may be a concrete beam cast integral with the shell to give added rigidity.
