Abstract

Abstract

By means of the modified iteration method,the nonlinear stability problem of a double-deck reticulated truncated circular shallow spherical shell under uniform pressure was investigated. According to the fundamental equations of double-deck reticulated circular shallow spherical shells,the critical buckling load for the shell with two types of boundary conditions was obtained and the effect of geometric parameters of the shell on the critical buckling load was discussed.
- double-deck reticulated,
