Outline of Final Research Achievements

In this study, a novel construction system using UHP-FRCC blocks which is completely reusable has been proposed. Since UHP-FRCC shows excellent mechanical performance even under tensile stress, the proposed system enable buildings to consist only of an unbonded connection without the need for reinforcing materials. Based on some results of numerical analyses and experimental studies, good potential of an UHP-FRCC block and its small structural members were confirmed. In addition, LCCO2 analyses of the proposed reusable construction system were carried out. As a results, reduction of environmental impact can be obtained because the proposed system can be adapted for changing social situation.
