Properties of Wood and Structural Wood Products
Wood differs from other construction materials because it is produced in a living tree. As a result, wood possesses material properties that may be significantly different from other materials normally encountered in structural design. Although it is not necessary to have an in-depth knowl edge of wood anatomy and properties, it is necessary for the engineer to have a general understanding of ...
متن کاملOptimum Structural Design with Discrete Variables Using League Championship Algorithm
In this paper a league championship algorithm (LCA) is developed for structural optimization where the optimization variables are of discrete type and the set of the values possibly obtained by each variable is also given. LCA is a relatively new metaheuristic algorithm inspired from sport championship process. In LCA, each individual can choose to approach to or retreat from other individuals ...
متن کاملStructural and other properties of modified wood
Wood is not under all circumstances an appropriate building material. Beside others, structural properties and biological durability determine the limits for the use of wood. Until recently, the only industrial applied method to improve the durability of wood was impregnating with toxic wood preservatives. Although much progress has been made in improving the fixation of preservatives (i.e. emi...
متن کاملCATSAT Structural Design Dr . Carl Wood ! Dr . Dave Forresi Brian McKinnon
CATSAT(Cooperative Astrophysical and Technology SATellite) is based upon an inexpensive, light, stiff and easily assembled structure. This paper details the overall design philosophy, manufacturing processes, and initial test results. The design utilizes flat aluminum panels that are screwed and bonded together, resulting in a stiff structure that costs less than $3000 and requires less than 40...
متن کاملDesign of solid wood panels with cross layers
The objective of this paper is to present a method for the design of solid wood panels with cross layers. The stress distribution in and the deformation behaviour of solid wood panels were analysed using the composite theory. The shear influence in solid wood panels was determined using the shear analogy method. A strength class system is proposed for the design of solid wood panels with cross ...
