Deformations of a Large Hall: Structural Design and Analysis,n of the displacement of the entire stucture with respect to the construction of the facade. In the following different problems with respect to the construction (e.g. realization of necessary gaps), structural analysis and assembly of the structure will be discussed in detail.

Thermo-Mechanical Coupling in Beam-to-Beam Contact, is presented. Contact surfaces are considered ideally smooth, so that the heat transfer due to radiation and convection in the micro cavities is neglected. In the physi-cal model of the beam material, only the linear thermal expansion is included and all the physical parameters are treated as independent of time and temperature.

On Different Variational Formulations of the Nitsche Method,for the Nitsche formulation are obtained: a) with Gauss point-wise substitution of Lagrange multipliers, b) with Bubnov-Galerkin-wise partial substitution of Lagrange multipliers. Both types of the Nitsche approach are implemented for 3D situations and a verification with a numerical example involving large sliding is presented.

On the Four-node Quadrilateral Element, equation to eliminate the additional incompatible degrees of freedom on the element level. With the resulting constant and linear gradient operators being uncoupled, the stiffness matrix is written in terms of underintegration and stabilization. Therefore, the new quadrilateral is labeled QS6.

,A Finite Element Formulation based on the Theory of a Cosserat Point – Modification of the Torsionae used as it was done for the original Cosserat point element posing the necessity to modify them. The reasons for the modification as well as the modified modes and results are presented in this paper.

A Brick Element for Finite Deformations with Inhomogeneous Mode Enhancement,h ensures objectivity of the element formulation and can be interpreted as a linear inhomogeneous deformation superposed by a finite homogeneous deformation. Examples show that the element is locking and hourglassing free and performs well for initially distorted meshes.

Hybrid and Mixed Variational Principles for the Geometrically Exact Analysis of Shells,l principles are shown to feature stationarity within the framework of the boundary-value-problem. The main features of the principles are highlighted, giving special attention to their relationships from both theoretical and numerical point of view.
