Corrugated Wood Composite Panels For Structural Decking

for an incompressible material is equal to 0.5. However, numerical errors occurred whenν of 0.5 is used in the FE model. In order to prevent numerical errors and to maintain thenear incompressible behavior of the adhesive at the same time, ν equal to 0.495 is used.Rigid elements are used for connecting the thin shell elements (corrugated panelRigid Bar Elementthickness of glue bond8-node 3D Brick ElementFigure 12: Non-rigid bond finite element model.or OSB), which are meshed at the middle of the panel skin thickness, to the 3D brickelements (nailed-glued bond). There are two nodes in one rigid element. The rotationsand displacements of both nodes are identical. Assignment of material properties is notrequired because the rigid element functions as a bridge to transfer the displacements androtations from nodes of one element to the other. For a typical composite deck mesh asshown in Figure 11, the displacements and rotations of the top thin shells mesh (for OSBunderlayment) are directly translated into the four nodes on the top of each 3D brickelement. Similarly, the displacements and rotations of the bottom four nodes areinfluenced by the thin shell mesh of corrugated panel at the bottom layer. The differencesof displacements between the top and bottom nodes of the 8-node brick element representthe interlayer slip between corrugated panel and OSB.26
