Elastic Buckling Behavior of Single Layer Latticed Cylindrical Roofs Under Snow Loading.

This paper aims at investigating the effect of the bearing length on the elastic buckling behavior of longitudinally stiffened girder webs subjected to patch loading. Buckling coefficients are calculated by means of linear finite element analysis. Furthermore, a parametric analysis is performed to study the influence of other geometric parameters such as the panel aspect ratio and the geometrical properties of the longitudinal ones. Buckling coefficients of longitudinally stiffened girder webs are computed numerically. The results show that the buckling coefficient for longitudinally stiffener girder webs increases with the loading length. However, this conclusion is considerably affected by other factors such as the position of the stiffener, and panel aspect ratios.

Nonlinear Buckling Analysis

In the present paper, the effect of imperfection on the elastic buckling load and mode shapes of externally-loaded single layer reticulated domes is investigated. The types of buckling concerned here are the general buckling, the local (dimple) buckling and the buckling of a member. As to the geometric parameter of a dome, the slenderness factor S is adopted which represents the openness and slenderness of the dome. The maximum value of the imperfection is assumed to be the normal random variable. The buckling loads are computed by the linear and the nonlinear buckling analysis using the finite element method. The statistical values are calculated by the three-points estimates method. The main points of interest are the influence of the shape and the extent of an imperfection on the buckling load.

Economic Considerations

Given the widespread use of beam and plate in structures, it is essential to have a thorough understanding of girder behavior. According to buckling failure mode in plates, it is necessary to take measures in this regard. Delta stiffener is using this approach. Due to the lack of technical knowledge about these kinds of plate beam, it is necessary to find good geometric properties of the delta girder plates for both technically and economically optimization. Therefore, in this paper, by modeling and finite element analysis for simple girder (without Stiffener), beam hardening by longitudinal plate and beam using delta hardening behavior are examined under the effect of the bending moment. Finite element analysis of elastic buckling analysis is included. With the above analysis, the effect of longitudinal stiffener and Delta Girders in terms of economic considerations has been studied. Keywords: Elastic Buckling, Beam, Plate, Stiffener.
