Development of Technologies for Residential Building Stock Reseneration by Removing Structural Walls and Beams

在1955年至1973年的大规模住房时代，日本各政府当局和公共住房公司建造了大量出租住房，以重建遭受战争破坏的城市，并容纳城市地区高度集中的人口。在日本所有出租的公共住宅楼中，约有40%是在大众住房时代后期(1965-1973)建造的。这些是四五层的钢筋混凝土建筑，其建筑框架足够坚固，可以承受几十年的更多使用，但其内部装饰和功能系统正在恶化。此外，这些居住单元现在太小了，因为这些居住单元被结构墙和梁分成了几个小空间。这项研究的目的是开发技术，通过拆除钢筋混凝土结构墙和梁，在这些劣化的住宅楼中逐一恢复居住单元。

In Japan, various government authorities and public housing corporations built a huge number of dwellings for rent to reconstruct war-damaged cities and to accommodate the high concentrations of population in urban areas in the mass-housing era between 1955 and 1973. Approximately 40% of all public residential buildings for rent in Japan were constructed in the latter mass-housing era (1965-1973). These are four- or five-story reinforced concrete buildings whose building frames are sufficiently strong to withstand several decades' more use but whose interior finishings and functional systems are deteriorating. In addition, these dwelling unit is now too small because the dwelling units are separated into small spaces by the structural walls and beams. The porpose of this research is to develop technologies for regenarating a dwelling unit one-by-one in these deteriorating residential buildings by removing structural walls and beams made of reinforced concretes.
