    We are constantly innovating socially to bring knowledge more closer and instant, at the same time trying to engage the community to help better connect the world. Non Technical Summary There are a multitude of timber structures that are more than 50 years old. Many are sound, while some have significant deterioration. This research focuses on .

    BRIDGE MAINTENANCE, REHABILITATION, AND REPLACEMENT: CASE HISTORIES Over time, bridges may become structurally or functionally deficient. Structurally, the deficiency can result from deterioration, damage, or increased load requirements in excess of the design capacity. Hydraulically, the original waterway opening under the bridge may be­. Carbon is bound in wood structures for a long time In buildings with wooden parts, the carbon stored in the wood is stored in structures that are long-term carbon stores. An average Finnish wooden house sequesters into its wooden structures about 30 tonnes of CO2 from the air.
