Behavior of R/C Cylindrical Panel Subjected to Combined Axial and Shear Loadings

Abstract

Reinforced concrete (R/C) cylindrical panels have been applied to the roof or the underground structures. Also, in constructing a high rise building, an R/C wall is often used to improve the lateral rigidity of the building comparing with beam column systems under wind or seismic loading. In this paper, the behavior of R/C cylindrical shell under combined axial and lateral shear loadings is analyzed numerically. R/C cylindrical shells are often adopted for the core wall system. R/C cylindrical panels are fixed at both hoop edges and are subjected to a lateral shear displacement after axial compressive load is applied in the meridional direction. In numerical analyses, the behavior of R/C cylindrical shell panel is analyzed under several combinations of axial and lateral loadings. The panels are modeled by use of the shell elements.
