Abstract—It is important to eliminate thermal bridge for achieving passive and environmental-friendly buildings. Structural members may frequently act as thermal bridges that become a conduit of energy. A thermal bridge breaker (TBB) system is effective to reduce energy transfer between inside and outside of a building. In order to be used for a structural member, the structural capacity of a TBB system should be larger than a demand resulting from external loads. This study concentrated on the development of a TBB system that will be applicable to connection between interior and exterior floors. The developed TBB system consists of anchorage devices and compression joints. The anchorage devices are used to ensure the continuity of reinforcements in inside and outside floors while the compression joints are used to resist compression stress occurring to the TBB system. Significantly high compressive stresses are usually applied to the compression joints since they are designed with relatively small section areas. This study carried out compressive tests of composite material which is developed to be used for compression joints in a TBB system. Based on test results, TBB systems are designed for the application of a typical floor system.
