| 摘要： | Existing applications of composite materials technology to the repair of timber structures were evaluated. Based on the prior state of the art, it was determined that a new composites-based repair approach was necessary if the material was to be used to its fullest and if ease of field application was a criterion. Sub-scale tests of this concept have been performed, and stiffness and strength have been monitored. The results indicate that significant damage can be overcome through the insertion of the pultruded fiberglass rods. The results also indicate that localized repair is possible with this approach and that stiffness can be adjusted by varying the number and position of the transverse composite rod. |
