This paper deals with the mechanical performances of thermal break for external steel structures (balconies, passageways) attached to a steel facade with external thermal insulation. The proposed solution is composed of a PVC or plywood layers inserted between an end-plate connection and a steel column. Static and cyclic tests are performed on a cantilever beam connected to a steel column by a thermal break in order to investigate the effect of the thermal insulation layer on the rotational stiffness, bending moment resistances and failure modes. These tests highlight on one hand the influence of the thermal insulation and on another hand, the bolt configuration (extended and flush end-plate, stiffeners, RHS or I profile). © SDSS 2019 - International Colloquium on Stability and Ductility of Steel Structures.
