Abstract

There are many efforts to reduce thermal bridge for achieving passive and environmental-friendly buildings which current construction markets increasingly pay attention to. In order to reduce energy transfer between inside and outside of a building, a thermal bridge breaker(TBB) system has been applied in many construction sites for the disconnected structural components such as balcony slab. In this case, thermal insulation could be enhanced by rearranging and minimizing of TBB system's structural components, although, structural capacity is inevitably reduced compared to existing balcony slab connection joints. With regard to the development of a new TBB system, their structural capacity should be larger than a demand resulting from external loads in order to be used for a structural member. This study carried out structural test of prototype cantilever slab which TBB systems are embedded in the connection joints. Based on the test results, this paper is to describe the technical interaction for developing improved TBB model which has an enhanced thermal insulation property and structural performance. constructablility when the parameter is over 50mm.
