Initiatives for Establishing Steel-structure Technologies for Earthquake and Tsunami Safety

摘要

In Japan, steel structures account for about 30-40% of the total floor area in new building construction starts by structural method, showing an extremely high rate of steel-structure application compared to steel-structure applications in foreign nations. When examining the floor area of steel-structure building construction starts by building height, low- and medium-rise buildings with five stories or lower account for more than 90%. Given this situation, in order to build safe and reliable towns, it is necessary to supply steel products that will help to secure the quality of steel-structure building frames and their resultant seismic resistance.
