Monitoring and Preservation of Wooden Bridges

Original language description

This paper deals with new monitoring method of wooden bridges by FBG sensors and chemical preservation on wood surface by planar particles of TiO2. The technology of Fiber Bragg Grating (FBG) sensors is an optical system used for the same purposes as strain gauge sensors. The system was tested under laboratory conditions when the fiber with the sensor was embedded into a beam structure of glued laminated timber. The beam was mechanically evaluated by a 4-point loading test until failure. The correct functionality of the sensor was examined. The technology of fiber optic sensors could be one of the ways to control the state of the bridges and also any other structures made not only of wood in the future. We are also trying to eliminate degradable factors by wood protection. Types of wood protection includes all measures which would protect wood from influences of fungi, insect, weather (temperature, humidity, wind, fire etc.) and can be divided into chemical protection and radiation protection. Chemical protection can be further divided into protection against weather, biological pests and against fire. In our work the solution of this weakness by photocatalytic materials (namely TiO2) will be discussed. Those materials are efficient UV absorbers and they are able to destroy biological aggressors as well. Nowadays, there is no information about the interactions between wooden surface and non-photoactive or photoactive form of TiO2. TiO2 exists in many morphological forms. The planar particles were chosen for purpose of the experimental investigation. They can be prepared as non-photoactive and photoactive. This material was applied on wooden surface for creating a transparent layer. Obtained data will be used for new evaluation method of influence photocatalytic materials on wooden surface.
