Non Technical Summary
Work in this problem area will provide information on important properties of wood and wood materials. This information will be useful to builders and building code officials.

Objectives Summary
The objective of research in this problem area is to develop methods for predicting the performance of wood-based structural products as a function of their constitutive components. With the expected growth in the use of engineered wood-based products in construction, and the restricted availability of higher quality sources of wood fiber, research on the basic properties of small-diameter softwoods, undervalued hardwoods, and recycled wood fiber in various forms is needed so that these sources of fiber can be used in engineered products. Research in this area will focus on developing analytical models of the relationships between constitutive properties and end-use performance characteristics.

Approach Summary
Planned attainments: 1) Basic information on the properties of cross laminated timber (CLT), especially dynamic performance data to be used in the design of disaster resistant housing; 2) Foundation information on the use of structural insulated panels (SIPS) in construction, in particular time-dependent performance characteristics; Information on the use of Stress Class Systems for structural lumber grading
