Progress 04/21/05 to 04/21/10
Outputs
FPL has completed a study to develop better performance based standards for hardboard siding. This work was conducted with financial assistance from the U.S. Department of Housing and Urban Development (HUD) and the American Hardboard Association (AHA). The final report has been published. FPL published a report on mechanical property loss and the occurrence of wood decay during experimental outdoor aging of wood-based panels. This problem area was terminated as part of a reorganization of work units at the Forest Products Laboratory.
Impacts
This work provides practical and fundamental information to help the composite wood industry produce more durable products for the consumer.

Progress 10/01/05 to 09/30/06
Outputs
The ratio of composite products to solid wood utilized in new construction is rising rapidly. A cooperative study with North Carolina State University is underway to identify design and construction practices that are moisture tolerant and robust for exterior walls that are sheathed with wood-based material and clad with an absorptive siding material for a variety of climates and exposures.

Progress 10/01/04 to 09/30/05
Outputs
FPL has completed a study to develop better performance based standards for hardboard siding. This work was conducted with financial assistance from the U.S. Department of Housing and Urban Development (HUD) and the American Hardboard Association (AHA). The final report has been published. A study on the effect of cyclical wetting and drying on decay of wood and oriented strandboard (OSB) has been completed. This work is supported by an inter-agency agreement with U.S. Department of Housing and Urban Development (HUD). A final report is in preparation
Impacts
This work provides practical and fundamental information to help the composite wood industry to produce more durable products to the public.

Progress 10/01/03 to 09/29/04
Outputs
The Forest Products Laboratory (FPL) continued the monitoring of the structural performance of a number of timber bridges at various locations in the United States. This research problem was transferred to FPL-4719.
Impacts
Research at the FPL is continuing as part of the Forest Service program on 'Wood in Transportation Structures.' Laboratory and field experimental studies together with analytical evaluations are aimed at formulating improved design criteria for conventional wood transportation structures and developing new types of structures that are more economical and allow for the extended use of underutilized species and new wood products.

Progress 10/01/02 to 09/30/03
Outputs
The Forest Products Laboratory (FPL) completed the final report for a 5-year cooperative bridge monitoring study with the Pennsylvania Department of Transportation. FPL also completed studies and reports on the environmental effects of creosote treatments and the effect of extreme cold temperatures on the performance of stress-laminated bridges.

Progress 10/01/01 to 09/30/02
Outputs
FPL completed a 3-year monitoring study on a bridge in Richland County, OH, and a 5-year cooperative bridge monitoring study with the Pennsylvania Department of Transportation. FPL also completed data analysis on field data collected from two stress-laminated glulam bridges in Wisconsin and Arizona. FPL also evaluated a remote data acquisition system for field monitoring of bridges.
