| 摘要： | Beaudette Consulting Engineers (BCE) of Missoula, Montana, requested assistance from the Forest Products Laboratory (FPL), Madison, Wisconsin, in mechanically grading lodgepole pine logs to use in building two cable suspension bridges in western Montana. The grading project is a demonstration of a proposed mechanical grading system developed by FPL in cooperative research studies with Timber Products Inspection, Inc. (TP), of conyers, Georgia, and the University of Idaho in Moscow, Idaho, Bridge design and selection of log design values are the responsibility of the engineering consulting firm. The project's objective is to provide the engineering firm with a variety of grade options for using small-diameter lodgepole pine logs more efficiently in these two engineered roundwood structures. |
