ABSTRACT
R/C cylindrical panels have been often used for the storage reservoir, tank, stack and cooling tower structures. They usually possess the high ultimate strength under lateral uniformly distribute loading. Therefore, they are used for the wall structure in underground or the roof structure. However, when R/C cylindrical panels have heavy roof structure such as the underground LNG tanks or they are huge structures such as tall stacks or the huge cooling towers, they are subjected to combined axial compressive and lateral flexural loadings. From the previous paper (Hara 2008), the comparisons between the numerical and the experimental results concerning R/C cylindrical shell panel under the concentrate or the distribute lateral loading were presented. In the analyses, R/C cylindrical shell were pin-supported on both meridional and hoop edges. Both numerical and experimental results were well agreed. In this paper, the deformation characteristics and the ultimate strength of R/C cylindrical panel subjected to a combined axial and a flexural loadings are investigated numerically under the same geometric and supporting conditions.
