Wood Pressure Embeded Tests And Theoretical Research On The Earthquake-resistant Design Of Wooden Structural Ductile Node

Structure is separated from the elements and components of the node from the collection together. Nodes are often the most critical structural component in many works, a control of the structural strength, stiffness and ductility of the important role. The wooden structure in extreme loads (such as earthquakes, typhoons) role in the collapse and destruction under the survey found, the poorly designed nodes are often the main reasons to lead to destruction of the structure. Wooden structure in the past often emphasis on structure and components, and neglect the nodes on the importance of structural safety. Wooden foreign researchers have gradually realized that these problems and efforts in this regard the research, attempt to change the structure of wood components and nodes in the research of the phenomenon of uneven development, to establish the wooden structure node design methods, based on the probability and reliability and tried to States into the wood structure design specifications.Wood is a more complicated mechanical properties of the orthotropic material. In order to find the relationship of the elastic-plastic materials and the elastic limits of stress and the presses parts, the thickness when the wood is pressed in different parts and different thickness. In this paper, select a different thickness of different parts of the specimen under pressure to the pilot study will compare that pine in different thickness, different parts of pressure and stress at the limits of elastoplastic elastic stiffness, and other changes in the law, to provide the basis nodes to the structural design i-n-wood Wooden structure designed.
