Advances in Steel Materials and Steel Structures in Japan

Abstract

<p>Over the course of 150 years since the construction of Japan's first cast iron bridge in 1868, Japan has become one of the most advanced countries in terms of steel structures. This advance is attributed largely to the contributions made by high performance steels. In Japan, steel material innovations have enabled progress in steel structures to leap forward, and in turn, challenging new structures has given birth to further advancements in steel materials. In this paper, the developments in steel structures and materials are reviewed and discussed. One conclusion drawn from this review and discussion is that steel still has the potential as a new emerging material to make further contributions to the advancement of steel structures.</p>

The effects of strain rate on the effective yield strength of high-strength steel at elevated temperatures

“…Earthquake-prone regions, such as Japan, require seismic designs for steel-based buildings. Therefore, the cross-sections of the steel members used for constructing high-rise and large-span structures in these regions must be greater than those in non-seismic regions (Kanno and Tsujii, 2015). However, to reduce the carbon dioxide (CO 2 ) emissions to combat global warming, the consumption of steel materials must be reduced.…”

“…There is an obvious demand in today's fast growing world economy for metropolitan and transportation infrastructures which offer both social resilience and durability under the threats posed by worsening global climates and natural disasters [1]. Up until now, steel has been the most favoured material for meeting this demand owing to its versatility and excellent mechanical properties.…”
