Modeling the initial curvature of members in the analysis of structural models
Aligerová, Jana ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
This bachelor’s thesis deals with the reaction of pressed indirect members in terms of their stability. Three models of indirect members with different types of curvature will be used for the solution – a member model with initial curvature, a member model with initial benting and a member model indirect due to load. For these three models, a parametric study of the member will be made in which a calculation will be performed on a member with initial properties identical for all types of models. In the next section, the dependence of critical force and initial deflection on the behaviour of the member models with initial curvature and benting will be investigated. Furthermore, the member design will be carried out in terms of load carrying capacity. In this design, a comparison will be made between the simplified method of calculation on the curved members and the design in terms of the buckling strength concept. The acquired knowledge in the field of stability theory on an indirect member will be applied to the real structure of the lookout tower Borůvka near Hluboká.
