Collapse behavior of double layer dome space structures depends on different factors such
as load pattern, material mechanical properties, and member's physical characteristics …

Probabilistic methods are used in engineering where a computational model contains
random variables. The proposed method under development: Direct Optimized Probabilistic …

Methods: The variation of imperfect members' positions and initial size of length
imperfections (being longer or shorter than the ideal size) were selected as the parameters …

Using finite element method to study the influence of geometric imperfections and welding
deformation on the global stability of orthogonal mixed with oblique single-layer reticulated …

Open-top storage tanks are prone to buckling under wind loads due to the lack of top
restraint. As a typical cylindrical shell, the buckling capacity is very sensitive to initial …

This study aimed to investigate the effect of initial member length an imperfection in the load
carrying capacity of double-layer domes space structures. First, for the member length …

单层网壳结构是缺陷敏感结构, 为降低结构稳定承载力对缺陷的敏感性, 提出以稳定承载力随
缺陷波动最小(等稳定) 为目标函数的单层球面网壳结构截面优化设计方法 …

In space domes, geometrical changes are the main factors that determine the forces in the
structural members. This paper has addressed the effects of the height-to-span ratio …

To improve the reliability of the stability and bearing capacity of grid shells, we proposed a
novel sequential two-level stochastic optimization based on the regional sensitivity …

Abstract The imperfections in Double Layer Grid Space Structure (DLGSS) threaten the
safety of designs. The imperfections in the member length of DLGSS may result from human …
