Part of: Structural Wood Research: State-of-the-Art and Research Needs


Wood as a renewable resource is briefly discussed to provide an understanding of the complex nature of the relationship between its availability and its efficient use for engineered construction. Potentials for optimizing wood resource utilization through the application of structural reliability concepts and the recognition of the unique behavior of wood structures are developed. Structural reliability is discussed from the viewpoint of the selection of appropriate safety levels and developing improved structural wood products. The interaction of the influence of strength variation and level of safety chosen on the required design factors for engineered wood structures is illustrated. The important distinction between wood structural systems with a high degree of load sharing and those which are dependent on the structural integrity of a single member is defined. Research developments required to achieve full potentials for optimizing engineered wood structures are enumerated.
