| 摘 要： | 采用三点弯曲的方法对杨木单板条层积材进行了30%和40% 2个应力水平的蠕变试验，并用四元件Burger模型对蠕变数据进行拟合。结果表明，四元件Burger模型很适合用于描述杨木单板条层积材的蠕变变形，且随着应力水平的增加，PSL的瞬时弹性变形增加。

| Abstract: | Creep behaviors of of poplar parallel strand lumber (PSL) under the loads of 30% and 40% were tested. The resultant data were analyzed by Burger model. The results indicated that the Burger model was suitable to describe the creep behaviors of poplar PSL, and the instantaneous elastic behavior would increase with the increase of loads. |
