Reducing embodied carbon in seismic design of new buildings

This article explores how to reduce embodied carbon in the seismic design of new buildings. Why this is important is discussed in terms of locating the 'seismic carbon' in a building. As the article is written for the everyday structural engineer rather than the seismic specialist, the fundamental concept of seismic engineering is explained, and how it differs from non-seismic design. Six key strategies for reducing seismic carbon are put forward. While straightforward and resembling non-seismic considerations, they reveal areas of particular importance to seismic design. Finally, perspectives and project examples from three different seismic regions around the world are presented – Taiwan, the Canadian Pacific rim, and the region combining the UAE and Saudi Arabia. While sharing some common challenges and approaches, the regions each display their own design trends based on their particular histories and design practices.
