| 摘要： | The goal of this study is to develop a reliable load rating methodology for timber piles based on the level of documented damage. The Bridge Maintenance Section 9f DOTD supplied approximately 30n deteriorated timber piles up to ten feet (3m) in length with a representative range of hollowness and splitting (checking). Small coupons were taken from each of the piles to determine the basic material properties. The degree of damage was quantified and each pile tested in axial compression. Mathematical models were developed to predict the axial load capacity and included all significant variables as typically reported by bridge inspectors. The theoretical and experimental results were compared to verify the model. Finally a recommended procedure was developed for load rating decayed timber piles. |
