This bachelor thesis deals with the static analysis of a curved beam with an axis of helical shape using the general stiffness method. The thesis focuses on the analysis displacements and cross-sectional forces on this type of beam structure. It consists of a space-curved beam that can be used in practice as an element of barrier-free construction. Unlike the practice where most commercial programs deal with corded structures with a curved central line modelled by n-polygonal axis, we derived the stiffness matrix and load vectors for the spatially curved beam, and these were used in the algorithm for an analysis of a space-curved beam structure loaded by a static load. The results obtained are sufficient for the preliminary design of a structure, a detailed static calculation, including dynamic effects, would have to be done for the definitive design required for the project. Finally some results of internal forces on the curved beam are presented, including some graphic schemes.
