長寿命化技術導入効果の経時変化を考慮した動的劣化ハザードモデル

抄録

Lifespan-extending technologies have been developed and put into practice for the purpose of inhibiting the deterioration of aged infrastructures. It is important to examine and evaluate the effects of such technologies, but in most cases, it is assumed that such technologies will remain effective forever. However, in the case of actual infrastructures, we cannot deny the possibility that the effects of them will decline with time. In detail, the effect of such technologies is evaluated with a change in deterioration hazard rate through the adoption, and it is assumed that the change can be represented by an effect function to formulate a dynamic deterioration hazard model. In addition, the authors confirm the effectiveness of the proposed method by applying it to a case of the waterproof layer of RC slabs.
