Abstract: “Reinforced concrete cylindrical shell with edge beam on meridional free edges was analyzed by use of FEM. As the edge beam on meridional edge, three kinds of rectangular beams were arranged. One was connected to the shell at the gravity center of the beam and the others were connected at the bottom or the top of the beam. The model was supported at four corner of R/C shell. Applied load was the external pressure. From the numerical analyses, the shell connected with the top of the beam showed the smooth deformation and the stress distributions as well as the highest load carrying capacity.”
