3D – Static Extension SchüCal

The research project “3D – Static Extension SchüCal” is a collaboration between Schüco International KG and the constructionLab from TH-OWL to further develop the software tool SchüCal in consideration of three-dimensional static beam structures. The research project was divided into several parts, facilitating the implementation of the application.

In the first phase, we formulate the theoretical basis for the implementation of non-tilting 3D beam elements in C++.  The routines include the calculation of element stiffness matrix, element load vector, assembling of global stiffness matrix, application of boundary conditions (supports) and hinges, solution for the overall equation system and provision of account deformations and intersection forces. At the nodes, free rotation in y and z and its combination enables the static calculation of horizontal and vertical beam elements with consideration of biaxial bending (without torsion).

In phase two, under development, the aim is to be able to carry out a structural analysis of general three-dimensional façade framework structures considering beam elements in any three-dimensional position. The element stiffness matrix and load vector are under further development to enable the calculation of uniform and non-uniform temperature effects and warp-free torsion (St. Venant torsion).

Additionally, a concept for testing the constraint-free support of facade structures will be included. The research project also provides technical documentation and support for the definition of required data structures and static verification, preparing examples for the test phase. The verification examples also include comparative results with other programs.
