Outline of Final Research Achievements

Reinforced concrete (R/C) shells have been used for roof structures of the buildings and industrial structures, such as tanks and silos. For R/C shells that lose their characteristics of continuity due to the constructional reasons, it is important to prevent the collapse of the structure due to the local bending and to maintain the structural advantages. In this research, the size and the application details of induced edge beams were analyzed. The results presented the fundamental data to make the design recommendation of R/C shell. From the analyses, following results were obtained: a) the edge beam had the optimum size. b) It was effective to join between the top of the beam and the shell neutral surface.
