ABSTRACT
Initially in this paper, a brief overview of a recently established COST Action “Sustainability of
fjpnstructions - an Integrated Approach, is given. Secondly, details are given ol recent research at Queen's University Belfast on two innovative forms of construction, both of which have the potential to be highly sustainable. The first is on un-reinforced concrete bridge desk slabs and the second is the development of a flexible concrete arch system for short span bridges with no steel reinforcement.
