| Research Abstract |
On the structural rigidity of modern timber bridges by many years past, the rigid reduction of the modern timber bridge past in about ten years will not be seen after a build about the structural rigidity. However, structural rigidity will fall to a suddenly about 40% after a construction in 20 years or more. In other words, it became clear that the residual strength decreased quantitatively to about60%. Furthermore, from the result of estimation of the durable years based on valuation of the residual strength of modern timber bridges, It is acquired the finding that can develop maintenance-preventionsystem which can presume the durable years probabilistically.
