Abstract (englisch):
Structures in various industries are exposed to dynamic loads. The dissipative properties
of adhesively bonded joints can contribute to the damping of dynamically stressed structures. Dy-
namic hysteresis tests are carried out to determine the damping properties of adhesively bonded
overlap joints by varying the geometry and test boundary conditions. The dimensions of the overlap
joints are full-scale and thus relevant for steel construction. Based on the results of experimental
investigations, a methodology is developed for the analytic determination of the damping proper-
ties of adhesively bonded overlap joints for various specimen geometries and stress boundary con-
ditions. For this purpose, dimensional analysis is carried out using the Buckingham Pi Theorem. In
summary, it can be stated that the loss factor of adhesively bonded overlap joints investigated within
this study is in the range between 0.16 and 0.41. The damping properties can particularly be in-
creased by increasing the adhesive layer thickness and reducing the overlap length. The functional
relationships of all the test results shown can be determined by dimensional analysis. ... mehr
