Three thick concrete hyperbolic paraboloid shells supported on elastic edge beams were tested. The shells were tested for vertical deflections for uniformly distributed loads and bending moments at various sections were calculated. A comparative study of bending moment profiles and bending moment contours of the shells is presented. Deflections and bending moments at various points of one of the shells for horizontal movement of the top of the short columns along the line joining the columns are also given. A comparison of maximum deflections and maximum positive bending moments of the shells was made with plates of similar sections supported on elastic edge beams.
