Abstract:
By using the software of ANSYS for finite element analysis, the end-pressure range of Pinus sylvestris L. finger jointed lumber for structural use under three different fitness ratio were modeled. According to the modeling results, the end-pressure range were 1.5-3.0 MPa, 2.0-3.5 MPa and 2.5-4.5 MPa respectively when the fitness ratio are 0, 0.1 and 0.3 mm. Comparing the modeling results with the experimental results, it indicated that the end-pressure range from the modeling result was narrower than that of the experimental results. Therefore, the modeling can be used to predict the optimum end-pressure for finger jointed lumber, which showed that the optimal value of Pinus Sylvestris L. finger jointed lumber for structural was 3.5 MPa.
