- Abstract:
-
Aiming at the static stability and ultimate bearing capacity of fasting grid shell structure, the nonlinear finite element method was used to study. The whole process of buckling mode and instability of fasting grid shell structure was investigated by two analysis methods, eigenvalue buckling analysis and nonlinear buckling analysis, and through large-scale geometric parameter analysis, the structural limit bearing force of sagittal span ratio, grid shell thickness, web section and other parameters was calculated when different values were obtained, and compared with the single-layer grid shell structure. The results show that the fasting grid shell structure is mainly instability as a whole, and the ultimate bearing capacity is 2.87 times higher than that of the single-layer grid shell structure under the same amount of steel.
