In this thesis, a shape grammar is created to divide a simplified bridge geometry in small planar modules in two-dimensions. The grammar can achieve a generative seg-mentation of the geometry. The shape grammar is programmed with the programming interface of the Sortal Grammar Interpreter (SGI). The segmentation suggestions are exported from CAD to numerical calculation program, in which an automated evalua-tion is implemented. The rating takes three points into account: The angle in a segment length of the edges and the main stress directions of joints. For the first two factors, it is necessary to identify the individual segments in the geometry. Therefore the geom-etry is transformed into a graph. Individual segments are then recognized by an algo-rithm that finds the shortest path. A finite element model is used, in which the main stress directions are computed. Finally, advantages as well as problems of the solution are described and evaluated.
