Thermal break elements with applications in seismic zones

Thermal break elements (Isokorb) are used for preventing thermal bridges in buildings. To ensure force transmission and thermal break, Isokorb elements are equipped with load bearing components and insulation material. In this paper the effects of seismic actions on the Isokorb elements are analyzed. A design method accounting for dynamical forces acting on balconies connected with Isokorb elements is investigated. In addition, the results of experimental tests are presented and compared with numerical modelling to verify the calculations methods. Finally, based on test results with Isokorb elements, the application of thermal break elements in seismic zones is verified by the proposed calculation method.
