TAC.T Bridge – pedestrian bridge of small diameter timbers and the environmentally friendly concrete

Abstract

TAC.T BRIDGE is a pedestrian bridge, composed of small diameter timbers and the environmentally friendly concrete, that will lead to sustainable action now and future. The site is at the Japanese General Contractor's R&,D department. This bridge functions as a part of a circular pathway, that connects the scattered facilities, and contributes not only to convenience for the researchers but also as a place for a change of pace during working time. As for the used material – small diameter timbers, which has been mainly used for frames of housing in small scale, is easy to procure in a stable price and to machine with precision on NC processing. And the environmentally friendly concrete, which achieves a reduction of CO2 emissions and a negative CO2 balance by replacing a part or all of cement to blast furnace slag and/or carbon‐recycled materials, comprises the bridges abutments. TAC.T BRIDGE is our proposal for the realization of the carbon neutrality by 2050.
