Eff ect of Boundary Conditions on the Behavior of Stiff ened and Un-Stiff ened Cylindrical Shells
Oussama Temami,Ashraf Ayoub,Djamal Hamadi,Imed Bennoui 한국강구조학회 2019 International Journal of Steel Structures Vol.19 No.3
The eff ect of boundary conditions is very important in the analysis of cylindrical shells, and is rarely studied in the literature due to its diffi cult experimental simulation. For large structures such as shell roofs, the type of boundary supports is among the major factors that can minimize the stresses and defl ections. In this study, experimental and numerical investigations of the eff ect of diff erent boundary supports for stiff ened and un-stiff ened cylindrical shells were conducted. Two diff erent models of the stiff ened and un-stiff ened cylindrical shells with diff erent boundary conditions, “pinned and with rigid diaphragms”, were studied. It was shown that by using rigid diaphragms for cylindrical shells, the defl ections are minimized by 80%, and by (45–50) % for the stiff ened cylindrical shells. From the experimental investigations and the numerical results obtained, the effi ciency of the proposed boundary support types for cylindrical shells is confi rmed, which can result in economic benefi ts.
