Buckling of reticulated laminated veneer lumber shells in consideration of the creep
AbstractThe constitutive model of laminated veneer lumber dealing with the creep and suitable for FE modeling was developed, based on the year-long tension and compression tests of laminated veneer lumber. The constitutive model was incorporated into the commercial FE software ABAQUS by developing a user-defined subroutine UMAT. FE models to predict the long-term behaviour of reticulated laminated veneer lumber shells, buckling in particular, were developed. Buckling analysis of single layer reticulated laminated veneer lumber shells with three-directional mesh was conducted. The interdependent relationship between the creep buckling load and the buckling time of the shells was revealed through the analysis, and the safety load against buckling during service life of the shells was defined.
