Creep Behavior of Movable Furniture Shelves Manufactured with Domestic Particleboard and Imported Douglas-fir and Lauan Solid

This study was carried out to investigate the creep behavior of domestic particleboard and imported Douglas-fir and lauan solid boards to evaluate the suitability of domestic particleboard as shelves for furni ture All shelves were cut into 20.0 by 94.0 em size and were subjected to a creep test under a uniformly distributed load of 0.022 kgf/cm2 for 96 hours. Total deflections of 15mm and 18mm thickness particleboard were very higher than those of Douglas-fir and White lauan solid during the testing periods. For all shelves, the values of relative creep increased linearly with time but creep modulus decreased during 96 hours. The predicted length over deflection ratios were 26.55 and 46.73 for 15mm and 18mm thickness particleboard. respectively, But the values for Douglas-fir and white lauan were 164.84 and 103.09, respectively. which were very higher than those of particleboard.
