Abstract
Plants and especially trees enrich buildings. They give shade and improve the
ambience, but also can cause damage to the buildings. Roots are biological soil
anchorages. The wind load, which may amount to several metric tons and acts on
lever arms that may exceed 50 meters in length, causes a high bending moment
at the butt of the stem. This bending moment is distributed over the roots into the
soil. Thereby, the roots often use structures in the surroundings of the tree like
pipes, walls, etc., for anchoring and apply loads to these structures. Loading
grows with tree height and root diameter, and when the loading caused by the
roots exceeds the strength of the structure, it will fail. Structures of stone are
especially sensitive against fatigue failure. In the present paper, examples of such
roothuilding interactions will be given. Furthermore, results of a
