CO2 Fixation Using a Composite Steel Timber Structure

Abstract

One approach to promote forest growth is the pruning and thinning of trees. In the field of building structure, it is necessary to use thinned woods as timber positively. However, timber is too weak to apply to the large-scale buildings. Research and development of a building system to use timber are demanded. Authors propose composite steel-timber structure aiming to spread wood to building construction field considering the global environment. First, distribution volumes of planted forest of each age forest class in Japan and its CO2 fixation are shown, investigating forest resources. Finally, the specific example of a composite steel-timber structure is shown and CO2 fixation at building structure model using a composite steel-timber structure is estimated.
