Abstract
A spatial-structural design process can be investigated via a so-called research engine, in which a spatial design is transformed into a structural design and vice versa. During the transformation from a spatial into a structural design, it is necessary to end up with a stable structural model, so that a (static or dynamic) structural analysis can be carried out. This paper presents a method to automate the (normally intuitively carried out) stabilization process, using data on a structural design's geometry and its instability modes. The method uses the null space and associated null vectors of the structural stiffness matrix. Then each null vector is solved by connecting one of the vector’s degree of freedom associated key points with a surrounding key point. Examples illustrate the method and demonstrate that predefined requirements have been met.
