To study the creep behavior of bamboo beams, the long-term bending creep tests of twelve bamboo beams with different loading levels were carried out in an indoor environment. The following results were obtained. The creep of reconstituted bamboo beams under different loading levels exhibits the three-stage characteristics of short rapid creep, sustained moderate-speed creep, and stable low-speed creep; the growth ratios of creep deflection are between 30.9% and 39.1% for the reconstituted bamboo beams at the 10–50% loading level. The creep and the creep rate increase with an increase in the loading level. Meanwhile, the long-term creep prediction model of the reconstituted bamboo beam is derived based on the Burgers model; the proposed model may reflect the significant effects of the loading level and is able to accurately evaluate the deflection-time behavior of the recombinant bamboo by taking the loading level into consideration. Based on the prediction, the creep value of reconstituted bamboo beams is large and develops rapidly, and the creep deflection of the reconstituted bamboo beams at high loading level (30–50%) will exceed the maximum deflection corresponding to the ultimate bending capacity within 5 years.

为了研究竹梁的蠕变特性，在室内环境下对十二种不同荷载水平的竹梁进行了长期弯曲蠕变试验。获得了以下结果。再生竹梁在不同载荷水平下的蠕变表现出三个阶段的特征：快速蠕变短，持续中速蠕变和稳定低速蠕变。在荷载水平为10％至5​​0％的情况下，重构竹梁的蠕变挠度增长率在30.9％至39.1％之间。蠕变和蠕变速率随负载水平的增加而增加。同时，基于Burgers模型推导了重构竹梁的长期蠕变预测模型。该模型可以反映负荷水平的显着影响，并且能够通过考虑负荷水平来准确评估重组竹的挠曲时间行为。根据预测，重构竹梁的蠕变值较大且发展迅速，在高载荷水平（30–50％）下重构竹梁的蠕变挠度将超过最大挠度，最大挠度对应于5年份。
